General Description

The MAX8831 integrates a 60mA, 28V PWM DC-DC step-up converter with five low-dropout LED current regulators for display and keypad backlighting in cell phones, PDAs, and other portable devices.

The IC provides up to 90% efficiency over the entire input voltage range of 2.7V to 5.5V.

The step-up converter operates at a fixed 2MHz switching frequency, enabling the use of very small external components to achieve a compact circuit area.

Key Features

open/short LED fault detection, output overvoltage protection, thermal shutdown, and open-circuit Schottky diode detection, with the status of each fault monitored continually for readback through the I2C interface. The MAX8831 is available in a tiny 2mm x 2mm, 16-bump WLP package. Features.
28V Step-Up DC-DC Converter Integrated NMOS Power Switch > 90% Efficiency Fixed 2MHz Switching Pulse Skipping for Improved Light-Load Efficiency Tiny External Components.
I2C Programmable.
