RT9284A-20GJ6E

Overview

The RT9284A-20GJ6E is a high-performance constant current switching regulator designed for white LEDs, manufactured by Richtek USA Inc. It operates within an input voltage range of 2.7V to 5.5V and supports a maximum output current of 100mA per channel. The device utilizes a boost topology with an internal switch and integrates PWM dimming capabilities. It is housed in a compact TSOT-23-6 package and functions reliably across a temperature range of -40°C to 85°C.

Feature Summary

Integrates an internal power switch for efficient constant current regulation
Supports precise PWM dimming control for brightness adjustment
Designed for compact applications using a small TSOT-23-6 package

Applications

White LED backlighting
Camera flash lighting systems

Procurement Notes

Verify the specific suffix GJ6E against official datasheets to confirm pinout and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure the supply voltage remains within the specified 2.7V to 5.5V range during operation.

Selection Notes

Select this component for designs requiring a single-channel constant current source with integrated switching capability. It is suitable for space-constrained portable electronics where low quiescent current and high efficiency are required. Verify that the external inductor selection matches the 1.2MHz switching frequency specifications.
