RT8568AGQW

Overview

The RT8568AGQW is a high-voltage LED lighting driver IC manufactured by Richtek Technology. It features a boost topology with six independent output channels, designed specifically for WLED applications. The device supports an input voltage range from 5.5 V to 40 V and delivers an adjustable output current between 5 mA and 40 mA per channel. It operates within a switching frequency range of 200 kHz to 2.1 MHz and includes integrated protection mechanisms such as overcurrent, overvoltage, and overtemperature protection. The component is housed in a WQFN-20 package and functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

Six-channel independent control for precise WLED backlighting management
Integrated PWM dimming capability for brightness adjustment
Comprehensive protection suite including overcurrent, overvoltage, and thermal shutdown

Applications

LCD panel backlighting systems
Mobile device display modules
Portable electronic equipment illumination

Procurement Notes

Verify the specific suffix and tape/reel specifications against the official datasheet before ordering. Confirm that the intended application environment remains within the specified operating temperature limits. Ensure compatibility with the host system's input voltage constraints. Check for any recent lifecycle status updates regarding obsolescence or replacement recommendations from the manufacturer.

Selection Notes

Select this component when a multi-channel solution is required for uniform LED distribution. Consider the wide input voltage range for flexibility in power supply design. Evaluate the thermal performance requirements given the high operating temperature rating. Compare pinout compatibility if replacing existing designs with similar multi-channel drivers.

Part Context

This part belongs to Richtek's family of high-voltage LED drivers optimized for portable electronics. It addresses the need for compact, efficient backlighting solutions in space-constrained devices. The integration of multiple channels reduces external component count compared to single-channel alternatives.
