RT8532AGQW

Overview

The RT8532AGQW is a white LED driver IC featuring a boost regulator topology designed for six-string LED configurations. It operates with an input voltage range of 2.5 V to 24 V and delivers a regulated output voltage of 43 V. The device supports an output current range from 5 mA to 50 mA and functions at a switching frequency of 1 MHz. Housed in a WQFN-20 package, it includes PWM dimming capabilities and overvoltage protection. The component is rated for operation between -40°C and +85°C.

Feature Summary

Integrates a boost regulator for driving multiple LED strings
Supports pulse-width modulation (PWM) dimming control
Includes built-in overvoltage protection circuitry

Applications

White LED lighting systems
Multi-string LED driver designs
General illumination applications requiring boost regulation

Procurement Notes

Verify the specific suffix 'GQW' against the manufacturer's official datasheet to confirm pinout and thermal specifications. Ensure compatibility with the required WQFN-20 footprint during PCB layout. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly to prevent package damage.

Selection Notes

Select this component when a single-channel boost driver is needed for up to six series-connected LEDs. Consider the 1 MHz switching frequency for passive component size reduction. Verify that the input supply voltage remains within the 2.5 V to 24 V range and that the load requires constant current regulation up to 50 mA.
