MAXIM INTEGRATED / ANALOG DEVICES MAX1574ETBT White LED Driver
The MAX1574 is a highly efficient white LED charge pump driver capable of supporting up to three LEDs with regulated constant current for uniform brightness. It offers adaptive 1x/2x charge-pump modes, achieving 180mA output drive across a 2.7V to 5.5V input range, making it suitable for portable devices like smartphones, cameras, and display backlights. Its fixed 1MHz switching frequency allows for small external components, and features like low EMI, input ripple, soft-start, and thermal shutdown ensure reliable operation. The device’s adjustable LED current based on an external resistor simplifies brightness control and dimming functions.
