LED Driver IC datasheet and documents for MAX8831EWE+

MAX8831EWE+

LED Driver IC Overview

The MAX8831EWE+ is a high-efficiency white LED step-up converter featuring an integrated 60mA, 28V PWM DC-DC boost stage and five low-dropout current regulators. It operates from an input voltage range of 2.7V to 5.5V with a fixed 2MHz switching frequency. The device includes two 25mA regulators for display backlighting and three 5mA regulators for keypad lighting. It supports I2C programming for output currents ranging from 50µA to 25.25mA and 50µA to 5.0mA respectively, enabling logarithmic dimming and individual blink control.

LED Driver IC Feature Summary

Integrates a 28V step-up DC-DC converter with five independent low-dropout LED current regulators
Supports I2C interface for programmable output current, logarithmic dimming, and ramp timers
Includes protection features such as open/short LED detection, thermal shutdown, and output overvoltage protection

LED Driver IC Applications

Display backlighting in cell phones and PDAs
Keypad lighting for portable devices
Signage backlighting systems

LED Driver IC Procurement Notes

Verify the exact suffix (e.g., +T) for packaging type, as the base part number may have variations. Confirm component status, as this series may be obsolete or discontinued depending on the specific revision. Ensure compatibility with 1.8V logic levels for the I2C interface during system integration.

LED Driver IC Selection Notes

Select this component for applications requiring high efficiency and compact design due to the 2MHz switching frequency allowing small external components. Choose based on the need for separate regulator channels for display and keypad LEDs. Verify that the 28V output capability matches the series LED configuration required for the target application.
