AP3036B Description
The AP3036B 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. Pin Assignments (Top View) Pin 1 Mark A constant frequency 1.0MHz PWM control scheme is employed in this IC, which means tiny external ponents can be used.
