RT9285CGQW

Overview

The RT9285CGQW is a high-performance, diode-embedded white LED driver manufactured by Richtek Technology Corporation. It features an integrated boost DC-DC converter and operates within a supply voltage range of 2.7V to 5.5V. The device supports PWM dimming control and delivers a switch current up to 400mA. Designed for compact applications, it utilizes an 8-pin WDFN EP package with exposed pad thermal enhancement.

Feature Summary

Integrates a boost DC-DC converter with embedded white LED driver functionality
Supports precise PWM dimming control for brightness adjustment
Features internal power switch for simplified external component count

Applications

Backlighting for mobile phones
Camera flash illumination systems
Portable electronic device displays

Procurement Notes

Verify the specific suffix 'CGQW' against the manufacturer datasheet to confirm pinout and thermal pad configuration. Ensure compatibility with system voltage requirements between 2.7V and 5.5V. Confirm that the 8-pin WDFN EP package aligns with PCB layout constraints and thermal management needs.

Selection Notes

Select this component when a small footprint and integrated boost topology are required for white LED driving. Consider the 400mA switch current limit and PWM dimming interface for application matching. Evaluate the 8-pin WDFN EP package for thermal dissipation and assembly feasibility in space-constrained designs.

Part Context

The RT9285 series belongs to Richtek's portfolio of tiny package, high-performance LED drivers. These devices are engineered for portable consumer electronics requiring efficient backlighting solutions. The CGQW variant specifically denotes the 8-pin WDFN EP packaging option within the product family.
