AP3036 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.
