ADUM6010 data sheet rev. a | page 12 of 16 applications informa tion the dc - to - dc converter section of the ADUM6010 works on principles that are common to most modern power supplies. it has split controller architecture with isolated pulse - width modulation (pwm) feed back. v ddp power is supplied to an oscillating circuit that switches cur rent into a chip - scale air core transformer. power transferred to the secondary side is rectified and regulated to a value between 3.15 v and 5.25 v depending on the set point supplied by an external voltage divider ( s ee equation 1 ). the secondary (v iso ) si de controller regulates the output by creating a pwm control signal that is sent to the primary (v ddp ) side by a dedicated i coupler data channel. the pwm modulates the oscillator circuit to control the power being sent to the secondary side. feedback allo ws for significantly higher power and efficiency. r1 r2 r1 v iso ) ( v 25 . 1 + = (1) w here: r1 is a resistor between v sel and gnd iso . r2 is a resistor between v sel and v iso . because the output voltage can be adjusted continuously there are an infinite number o f operating conditions. this data sheet addresses three discrete operating conditions in the specifications tables. many other combinations of input and output voltage are possible; figure 13 depicts th e supported voltage combinations at room temperature. figure 13 was generated by fixing the v iso load and decreasing the input voltage until the pwm was at 80% duty cycle. each of the curves represents the minimum input voltage t hat is required for operation under this criterion. for example, if the applica - tion requires 30 ma of output current at 5 v, the minimum input voltage at v ddp is 4.25 v . figure 13 also illustrates why the v ddp = 3.3 v input and v iso = 5 v configuration is not recommended. even at 10 ma of output current, the pwm cannot maintain less than 80% duty factor , leaving no margin to support load or temperature variations. typically , the a dum6010 dissipates about 17% more power between room temp erature and maximum temperature; there - fore, the 20% pwm margin cover s temperature variations. the ADUM6010 implements undervoltage lockout (uvlo) wi th hysteresis on the primary and secondary sides i/o pins as well as the v ddp power input. this feature ensures that the converter does not go into oscillation due to noisy input power or slow power - on ramp rates. pcb layout the ADUM6010 digital isolator , with a 0.15 w iso power integrated dc - to - dc converter , require s no external interface circuitry for the logic interfaces. power supply bypass ing with a low esr capacitor is required as close to the chip pad s as possible. the iso power inputs require several passive components to bypass the power effectively as well as to set the output voltage and to bypass the core voltage regulator (see figure 16 through figure 18). pdis v ddp gnd p 10 f 0.1 f + 8 9 10 1 1043-013 figure 16 . v ddp bias and bypass components v sel v iso gnd iso 10 f 0.1 f + 10k ? 30k ? 13 12 11 1 1043-014 figure 17 . v iso bias and bypass components the power supply section of the ADUM6010 uses a 125 mh z oscillator frequency to efficiently pass power through its chip - scale transformers. bypass capacitors must do more than one job and must be chosen carefully. noise suppression requires a low inductance, high frequency capacitor; ripple suppression and p roper regulation require a large value bulk capacitor. these capacitors are most conveniently connected between pin 9 and pin 10 for v ddp and between pin 11 and pin 12 for v iso . to suppress noise and reduce ripple, a parallel combination of at least two capacitors is required. the recommended capacitor values are 0.1 f and 10 f for v dd1 . the smaller capacitor must have a low esr; for example, use of an npo or x5r ceramic capacitor is advised. ceramic capacitors are also recommended for the 10 mf bulk c apacitance. an additional 10 nf capacitor can be added in parallel if further emi/emc control is desired. note that the total lead length between the ends of the low esr capacitor and the input power supply pin must not exceed 2 mm. gnd p gnd iso v se l pdis v dd p v iso gnd p by p ass < 2mm gnd iso ADUM6010 1 1043-015 figure 18 . recommended pcb layout in applications involving high common - mode transients, design the board layout such that any coupling that does occur equally affects all pins on a given component side. failure to ensure this can cause voltage differ entials between pins, exceeding the absolute maximum ratings specified in table 13 , and thereby leading to latch - up and/or permanent damage.
data sheet ADUM6010 rev. a | page 13 of 16 thermal analysis the ADUM6010 consist of two internal die attached to a split lead frame with two die attach paddles. for the purposes of thermal analysis, the chip is treated as a thermal unit, with the highest junction temperature reflected in the ja from table 8 . t he value of ja is based on measurements taken with the parts mounted on a jedec standard, 4 - layer board with fine width traces and still air. under normal operating conditions, the ADUM6010 can operate at full load across the full temperature range without derating the output current. power dissipation in the part varies with ambient temperature due to the characteristics of the switching and rectification elements. figure 14 an d figure 15 show the relationship between total power dissipation at two load conditions and ambient temperature. this information can be used to determine the junction temperature at various operating conditions to ensure that the part does not go into thermal shutdown unexpectedly. emi considerations the dc - to - dc converter section of the ADUM6010 components must, of necessity, operate at a very high frequency to allow efficient p ower transfer through the small transformers. this creates high frequency currents that can propagate in circuit board ground and power planes, causing edge and dipole radiation. grounded enclosures are recommended for applica - tions that use these devices. if grounded enclosures are not possible, follow good rf design practices in the layout of the pcb. see the an - 0971 application note at www.analog.com for the most current pcb layout recommendations for the ADUM6010 . insulation lifetime all insulation structures eventually break down when subjected to voltage stress over a sufficiently long period. the rate of insulation degra dation is dependent on the characteristics of the voltage waveform applied across the insulation. analog devices conducts an extensive set of evaluations to determine the lifetime of the insulation structure within the ADUM6010 . accelerated life testing is performed using voltage levels higher than the rated continuous working voltage. acceleration factors for several operating conditions are determined, allowing calculation of the time to failure at the worki ng voltage of interest. the values shown in table 14 summarize the peak voltages for 50 years of service life in several operating conditions. in many cases, the working voltage approved by agency testing is higher than the 50- yea r service life voltage. operation at working voltages higher than the service life voltage listed leads to premature insulation failure. the insulation lifetime of the ADUM6010 depends on the voltage w aveform type imposed across the isolation barrier. the i coupler insulation structure degrades at different rates, depending on w hether the waveform is bipolar ac, unipolar ac, or dc. figure 19, figure 20, and figure 21 illustrate these different isolation voltage waveforms. bipolar ac voltage is the most stringent environment. a 50 - year operating lifetime under the bipolar ac condition determines the analog devices recommended maximum working voltage. in the case of unipolar ac or dc voltage, the stress on the insulation is significantly lower. this allows operation at higher working voltages while still achieving a 50 - year service life. the working voltages listed in table 14 can be applied while maintaining the 50- year minimum lifetime, provided the voltage conforms to either the unipolar ac or dc voltage cases. any cross - insulation voltage waveform that does not conform to figure 20 or figure 21 must be treated as a bipolar ac waveform, and its peak voltage must be li mited to the 50 - year lifetime voltage value listed in table 14. 0v rated peak voltage 1 1043-016 figure 19 . bipolar ac wa veform 0v rated peak voltage 1 1043-017 figure 20 . dc waveform 1 1043-018 0v rated peak voltage notes 1. the voltage is shown as sinu soidal for illustration puposes only. it is meant to represent any voltage waveform varying between 0v and some limiting value. the limiting value can be positive or negative, but the voltage cannot cross 0v. figure 21 . unipolar ac waveform
