WHITE LED STEP-UP CONVERTER
AP3036/A
General Description
The AP3036/A is an inductor-based DC/DC converter designed to drive up to eight white LEDs in series for backlight. Only one feedback resistor is needed to control the LED current and obtain required brightness.
A constant frequency 1.0MHz 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 is sufficient. Additionally, the Schottky diode in boost circuit is integrated on this chip. The AP3036/A also provides a disable pin to ease its use for different systems.
