MAX1848 White LED Step-Up Converter

The MAX1848 drives white LEDs with a constant current to provide backlight in cell phones, PDAs, and other hand-held devices. The step-up converter topology allows series connection of the white LEDs so that the LED currents are identical for uniform brightness. This configuration eliminates the nee.

MAX1848 Features

* o Constant Current Regulation for Uniform Illumination o High 87% Efficiency o Analog or Logic Control of LED Intensity o 0.8W Output Power with Internal High-Voltage MOSFET Switch o Small, Low-Profile External Components o 2.6V to 5.5V Input Range o 13V Maximum Output with Overvoltage Protection o
