3. TECHNICAL BRIEF
3.12 LCD back light illumination
MAX8630W is a charge pump designed to support PWM control mode. And MAX8630W supports 5
white LEDs. The MAX8630W is capable of driving up to 5 LEDs at a total of 100mA(MAX8630W
100mA).
The current sinks may be operated individually or in parallel for driving higher current LEDs. To
maximize power efficiency, the charge pump operates in 1X, 1.5X, or 2X mode, where the mode of
operation is automatically selected by comparing the forward voltage of each LED with the input
voltage.
