1/53 xc9504 series 2 ch. step-up / inverting dc/dc controller ics general description the xc9504 series are pwm control, pwm/pfm switching, 2 c hannel (step-up and inverting) dc/dc controller ics. with 0.9v of standard voltage supply internal, and using exte rnally connected components, the output 1 voltage (step-up dc/dc controller) can be set freely within a range of 1.5v ~ 30v. since output 2 (inverting dc/dc controller) has a built-in 0.9v reference voltage (accuracy 2%), a negative voltage can be set with the external components. with a 180khz frequency, the size of the external components can be reduced. oscillation frequencies of 300khz are also available as custom designed products. the control of the xc9504 series can be switched betwee n pwm control and pwm/pfm automat ic switching control using external signals. control switches from pwm to pfm during lig ht loads when automatic switch ing is selected and the series is highly efficient from light loads through to large output currents. noise is easily reduced with pwm control since the frequency is fixed. the series gives freedom of control selection so that control suited to the applic ation can be selected. soft-start time is internally set to 10ms (output 1) which of fers protection against rush currents and voltage overshoot when the power is switched on. applications ? power supplies for lcd ? pdas ? palm top computers ? portable audio systems ? various multi-function power supplies features 2ch. dc/dc controller (step-up + inverting) output voltage range : 1.5v ~ 30v (set by fb1 pin) output current : more than 20ma ??????

7/53 xc9504 series note: *1 although the ic's step-up switch ing operations start from a v dd of 0.8v, the output voltage and oscillation frequency are stabilized at v dd ? 2.0v. therefore, a v dd of more than 2.0v is recommended when v dd is supplied from v in or other power sources. *2 although the ic's operations start from a v in of 0.9v, the ic's power supply pin (v dd ) and output voltage monitor pin (fb1) should be connected to v out1 . with operations from v in =0.9v, the 2nd channel's (output 2) en2 pin should be disabled. once output voltage v out1 is more than 2.0v, the en2 pin should be enabled. *3 please be careful not to exceed the breakdown voltage level of the peripheral parts. *4 effi={ [ (output voltage) x (output current) ] / [ (input volt age) x (input current) ] } x 100 electrical characteristics (continued)
8/53 xc9504 series operational explanation the xc9504 series are dual dc/dc (step-up + inverting) converter controller ics with built-in high speed, low on resistance buffers. error amplifier 1 is designed to monito r the output voltage and it compares the feedback voltage1 (fb1) with the reference voltage vref1. in response to feedback of a voltage lower than the reference voltage vref1, the output voltage of the error amp. decreases error amplifier 2 is designed to monitor the output voltage a nd it compares the feedback voltage 2 (fb2) with the reference voltage vref 2. in response to feedback of a voltage lower t han the reference voltage vref2, the output voltage of the error amp. decreases. this circuit generates the internal reference clock. the ramp wave generator generates a saw-tooth waveform based on outputs from the osc generator. the pwm comparator compares outputs from the error amp. and saw-tooth waveform. when the voltage from the error amp's output is low, the external will be set to on. this circuit generates pfm pulses. control can be switched between pwm control and pwm/pfm automatic switching control using external signals. the pwm/pfm automatic switching mode is se lected when the voltage of the pwm1 (2 ) pin is less than 0.2v, and the control switches between pwm and pfm automatically depending on the load. as the pfm circuit generates pulses based on outputs from the pwm comparator, shifting between modes occurs smoothly. pwm control mo de is selected when the voltage of the pwm1 (2) pin is more than 0.65v. noise is easily reduced with pwm control since the oscillation frequency is fixed. control suited to the application c an easily be selected which is useful in audio applications, for example, where traditionally, efficiencies have been sacrificed during stand-by as a result of using pwm control (due to the noise problems associated with the pfm mode in stand-by). the reference voltage, vref1 (fb1 pin voltage)=0.9v, is adj usted and fixed by laser trimming (for output voltage settings, please refer to the functional settings notes below.). to protect against inrush current, when the power is switched on, and also to protect against voltage overshoot, soft-start time is se t internally to 10ms. it should be noted, however, that this circuit does not protect the load capacitor (c l ) from inrush current. with the vref voltage limited, and depending upon the input to error amp 1, the operation maintains a balance between the two inputs of error amps and controls the ext pin's on time so that it doesn't increase more than is necessary. the reference voltage, vref2 (fb2 pin voltage)=0. 9v, is adjusted and fixed by laser trimming. this function controls the operation and s hutdown of the ic. when the voltage of the en1 or en2 pins is 0.2v or less, the mode will be disable, the channel's operations will stop and the ext1 pin will be ke pt at a low level (the external n-ch mosfet will be off) and the ext2 pin will be kept at a high level (the external p-ch mosfet will be off). when both en1 and en2 are in a state of chip disable, cu rrent consumption will be no more than 3.0 a. when the en1 or en2 pin's voltage is 0.65v or more, the mode will be enable and operations will recommence. with channel one (output 1) soft-start, 95% of the set output voltage will be reached within 10msec (typ.) from the moment of enable.
9/53 xc9504 series < output voltage setting, ch.1 (step-up dc/dc converter controller) > output voltage can be set by adding exter nal split resistors. output voltage is determined by the following equation, based on the values of r fb11 and r fb12 . the sum of r fb11 and r fb12 should normally be 1 m
or less. v out1 =0.9 (r fb11 +r fb12 )/r fb12 the speed-up capacitor for phase compensation's (c fb1 ) value should be adjusted using the formula fzfb=1/(2 c fb1 r fb11 ) so that it equals 12khz. depending on the application, the inductance val ue l, and the load capacity value c l , adjustments to this value are suggested so that the value is somewhere between 1khz to 50khz. [calculation example] when r fb11 = 470k

or less. the equation uses ch 1's (v out1 ) output voltage calculation method for the reference voltage. v out2 = (0.9-v out1 ) (r fb21 /r fb22 ) + 0.9v [calculation example] when r fb21 =17.5k

by the equation below. v out2 = (0.9 - v out1 ) x (r fb21 / r fb22 ) + 0.9 when the light load, c fb21 =0.1 f or lower value can be used. therefore, when c fb21 =0.027 f, time_ss2 = 5.0ms and v out2 = 95% of setting value (0.9-v out2 ) r fb22 ) (v out1 ? 0.9) r fb21 ) 3. channel 2 (inverting): withstand voltage of transistor the voltage applied between the drain and source is the sum of v in and v out2 . select a transistor with an absolute v dss rating that is suitable for your operating conditions. example: the voltage applied across v ds of a transistor will be 20.0v if v in = 5.0 v and v out2 = -15.0 v. under this condition, a transistor with v dss higher than 20.0v should be selected. (use a transistor with v dss that is 1.5 times the applied voltage or more, as a standard.)
