AP3036B WHITE LED STEP-UP CONVERTER 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 components 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 AP3036B also provides a disable pin to ease its use for different systems. CTRL 1 VOUT 2 VIN 3 6 FB 5 GND 4 SW The output overvoltage protection is implemented in AP3036B.
