AP3030 Datasheet | BCD Semiconductor

Data Sheet WHITE LED STEP-UP CONVERTER General Description The AP3030 is an inductor-based DC/DC converter designed to drive up to eight white LEDs in series or 2 rows of LEDs with 5 for each in parallel for backlight. Only one feedback resistor is needed to control the LED current and obtain required brightness. A constant frequency 1.2MHz PWM control scheme is employed in this IC, which means tiny external ponents can be used. Specifically, 1mm tall inductor and 0.22µF output capacitor for a typical application are sufficient. Additionally, the schottky diode in boost circuit is integrated on this chip. AP3030 also provides a disable pin to ease its use for different systems. The...
