MAX1576 – 480mA White LED 1x/1.5x/2x Charge Pump for Backlighting and Camera Flash
The MAX1576 charge pump drives up to 8 white LEDs with regulated constant current for uniform intensity. The main group of LEDs (LED1-LED4) can be driven up to 30mA per LED for backlighting. The flash group of LEDs (LED5-LED8) are independently controlled and can be driven up to 100mA per LED (or 400mA total). By utilizing adaptive 1x/1.5x/2x charge-pump modes and very-low-dropout current regulators, the MAX1576 achieves high efficiency over the full 1-cell lithium-battery voltage range. The 1MHz fixed-frequency switching allows for tiny external components, and the regulation scheme is optimized to ensure low EMI and low input ripple.
