LED Driver IC datasheet and documents for MAX1576ETG

MAX1576ETG

LED Driver IC Overview

The MAX1576ETG is a white LED driver IC featuring a switched-capacitor charge pump topology. It supports 1x, 1.5x, and 2x conversion ratios to drive single or multiple white LEDs from a 3.6V supply. The device delivers up to 480mA output current with a low-level output capability of 100mA. Operating at a 1MHz frequency, it functions within a -40°C to +85°C temperature range in a TQFN-24 package.

LED Driver IC Feature Summary

Integrates a charge pump with selectable voltage multiplication ratios for flexible LED driving configurations.
Includes overtemperature protection to ensure safe operation under thermal stress.
Supports efficient brightness control for battery-operated applications.

LED Driver IC Applications

Mobile phone camera flash lighting
LCD backlighting systems
Battery-powered portable devices

LED Driver IC Procurement Notes

Verify the specific suffix (e.g., ETG vs. ETG+) against the manufacturer's official datasheet to confirm lead-free status and exact electrical specifications. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the TQFN-24 package footprint matches the design requirements.

LED Driver IC Selection Notes

Select this component when a compact solution for driving white LEDs from a single-cell lithium-ion battery is required. Consider the 1MHz switching frequency for smaller external passive components. Evaluate the 480mA current limit against the target LED forward voltage and desired brightness levels.

LED Driver IC Part Context

This part belongs to the MAX1576 series of LED drivers designed by Maxim Integrated, now part of Analog Devices. It is categorized under Power Management ICs (PMIC) specifically for LED drivers. The family focuses on charge pump-based solutions for portable electronics requiring high-efficiency white LED illumination.
