LTC3210EPD-1#PBF

LED Driver IC Overview

The LTC3210EPD-1#PBF is a five-output LED driver IC manufactured by Analog Devices Inc. It utilizes a switched capacitor charge pump topology to regulate current for backlight applications. The device operates within an input voltage range of 2.9V to 4.5V and supports a switching frequency of 800kHz. It provides regulated output currents of 25mA and 400mA across its channels. The component is housed in a 16-lead UFQFN package measuring 3mm x 3mm with an exposed pad, designed for surface-mount installation.

LED Driver IC Feature Summary

• Integrates a switched capacitor charge pump topology for efficient DC-DC regulation without requiring external inductors.
• Provides five independent regulated output channels suitable for multi-zone or uniform LED backlighting requirements.
• Supports dimming control functionality to adjust LED brightness levels dynamically.

LED Driver IC Applications

• LED backlighting systems
