general description the max8630y/MAX8630Z charge pumps drive up to 5 white leds with regulated constant current up to 125ma total. by utilizing adaptive 1x/1.5x charge-pump modes and very low-dropout current regulators, they achieve high efficiency over the full 1-cell li+ battery input volt- age range. the 1mhz fixed-frequency switching allows for tiny external components, and the regulation scheme is optimized to ensure low emi and low input ripple. an integrated derating function protects the leds from overheating during high ambient temperatures. the max8630y/MAX8630Z are factory trimmed for full- scale led current options of 15ma, 18ma, 20ma, and 25ma. the MAX8630Z uses two enable inputs (enm for 3 main leds and ens for 2 sub leds) for simple on/off control and single-wire, serial-pulse dimming in 32 linear steps. the max8630y uses a single direct pwm input (pwm) to control all 5 leds with dc current proportional to the pwm duty cycle. if both enm and ens (or pwm) are kept low for more than 4ms, the max8630_ enters shutdown. the max8630y/MAX8630Z are available in a 14-pin, 3mm x 3mm tdfn package (0.8mm max height). applications display backlight (up to 5 leds) main (3 leds) + sub (2 leds) displays cell phones and smartphones pdas, digital cameras, and camcorders features ? 93% max/85% avg. efficiency (p led /p batt ) over li+ battery discharge ? 1% led current accuracy ? 125ma total drive capability ? adaptive 1x/1.5x mode switchover ? single-wire, serial-pulse dimming (MAX8630Z) independent on/off/dimming for main and sub linear?ull, 31/32nd, 30/32nd, ?1/32nd ? direct-pwm dimming (max8630y) ? 15, 18, 20, and 25ma full-scale versions ? low 0.1? shutdown current ? soft-start eliminates inrush current ? output overvoltage protection ? thermal-derating function protects leds ? 14-pin, 3mm x 3mm tdfn package max8630y/MAX8630Z 125ma 1x/1.5x charge pumps for 5 white leds in 3mm x 3mm tdfn ________________________________________________________________ maxim integrated products 1 1234567 14 13 12 11 10 9 8 led2 led1 led3 led5 c2p c2n in c1n gnd tdfn 3mm 3mm top view ( ) are for max8630y enm (cpwm) ens (pwm) c1p out max8630y MAX8630Z led4 pin configuration ordering information MAX8630Z 1 f 1 f 1 f 1 f in gnd enm ens out c1p c1n main output sub c2p c2n enable main on/off and dimming enable sub on/off and dimming input 2.7v to 5.5v led1 led2 led3 led4 led5 typical operating circuit 19-3689; rev 1; 2/07 for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. ordering information continued at end of d ata sheet. evaluation kit available part pin- package top mark pkg code max8630y etd15+t 14 tdfn (3mm x 3mm) aas t1433-2 selector guide appears at end of data sheet. note: all devices are specified to operate over the -40? to +85? operating temperature range. + denotes a lead-free package.

max8630y/MAX8630Z 125ma 1x/1.5x charge pumps for 5 white leds in 3mm x 3mm tdfn 8 _______________________________________________________________________________________ detailed description the max8630_ charge pump drives up to 5 white leds (3 main leds and 2 sub leds) with regulated constant current for uniform intensity. by utilizing adaptive 1x/1.5x charge-pump modes and very low-dropout current regu- lators, it achieves 125ma guaranteed output-drive capa- bility and high efficiency over the 1-cell li+ battery input voltage range. 1mhz fixed-frequency switching allows for tiny external components and the regulation scheme is optimized to ensure low emi and low input ripple. the MAX8630Z provides independent on/off/dimming control for main and sub displays (see figure 1). the max8630y allows direct-pwm dimming of all five leds together (see figure 2). a functional diagram for the MAX8630Z/max8630y is shown in figure 3. 1x to 1.5x switchover when v in is higher than v out , the max8630_ operates in 1x mode and v out is pulled up to v in . the internal current regulators regulate the led current. as v in drops, v ledmin_ eventually falls below the switchover threshold of 88mv, and the max8630_ starts switching in 1.5x mode, and v ledmin is regulated to 122mv by the charge pump. to switch back to 1x mode, the max8630_ determines if v in - v out is sufficient to keep v ledmin greater than 88mv. the comparator that makes this judgment is adaptive and matches the switchover for the conditions. soft-start the max8630_ includes soft-start circuitry to eliminate inrush current at turn-on. when starting up, the output capacitor is charged directly from the input with a ramped current source (with no charge-pump action) until the output voltage approaches the input voltage. once this occurs, the charge pump enters 1x mode, and the led output current is then ramped up in 32 lin- ear steps. if the current regulators are in dropout at the end of this time, the charge pump switches to 1.5x mode and the current regulators are ramped again. if the output is shorted to ground (v out < 1.25v), the part stays in the initial soft-start stage and output current is limited by the ramped current source. additionally, when the main or sub led current rolls over from 1/32 to full, the led current regulators soft-start again to eliminate input current spikes. enm/ens dimming control (MAX8630Z) when the leds are enabled (by driving en_ high), the MAX8630Z goes through soft-start and brings the led current up in 32 linear steps. dim the MAX8630Z by puls- ing en_ low (500ns to 500? pulse width). each pulse reduces the led current by 1/32nd. after 31 pulses, the current reaches 1/32, and the next pulse restores the cur- rent to 100%. figure 4 shows a timing diagram for en_. if dimming control is not required, enm and ens work as simple on/off controls. drive enm/ens high to enable the leds, or drive enm/ens low for shutdown. the leds operate at 100% brightness under these sim- ple on/off conditions. pwm dimming control (max8630y) dim the max8630y by applying a direct-pwm logic- level signal to pwm. an internal resistor combined with the capacitor at cpwm forms a lowpass filter that con- verts the pwm signal to dc led current that is propor- tional to the pwm signal? duty cycle. all five leds are controlled together on the max8630y. the pwm fre- quency range is 900hz to 200khz. if dimming control is not required, pwm works as a sim- ple on/off control. drive pwm high to enable the leds, or drive pwm low for shutdown. 1 0 2 3 4 5 27 28 29 30 31 32 shutdown t shdn 4ms 2/32 1/32 3/32 4/32 5/32 6/32 27/32 28/32 29/32 30/32 31/32 31/32 shutdown full full i led_ en_ t soft-start initial t hi t lo t hi > 50 s >500ns 500ns to 500 s figure 4.

(or 4.7?) cuts input ripple in half (or in fourth) with only a small increase in footprint. the 1x mode always has very low input ripple. component selection ceramic capacitors are recommended due to their small size, low cost, and low esr. select ceramic capacitors that maintain their capacitance over temper- ature and dc bias. capacitors with x5r or x7r temper- ature characteristics generally perform well. see table 1 for a list of recommended components. using a larg- er value input capacitor helps to reduce input ripple (see the input ripple section). pc board layout and routing the max8630_ is a high-frequency, switched-capacitor voltage regulator. for best circuit performance, use a solid ground plane and place c in , c out , c1, and c2 as close to the max8630_ as possible. see the MAX8630Z evaluation kit for an example layout. chip information process: bicmos table 1. recommended components designation value manufacturer part number description taiyo yuden jmk105 bj105mv 1? ?0%, 6.3v x5r ceramic capacitors (0402) c in , c out , c1, c2 1? tdk c1005x5r0j105m 1? ?0%, 6.3v x5r ceramic capacitors (0402) d1?5 nichia nscw215t white leds
