RT9285AGJ6

Overview

The RT9285AGJ6 is a DC-DC step-up LED driver IC manufactured by Richtek USA Inc., designed for backlight applications. It features an internal switch capable of delivering up to 400mA switching current and operates with PWM dimming control. The device functions within a supply voltage range of 2.7V to 5.5V and utilizes a 1MHz switching frequency. It is housed in a TSOT-23-6 package, suitable for surface mount installation, and supports an operating temperature range from -40°C to 85°C.

Feature Summary

Integrates an internal power switch for compact circuit design
Supports high-frequency PWM dimming for precise brightness control
Utilizes boost topology to drive white LEDs efficiently

Applications

LED backlighting systems
Mobile device displays
Portable electronic equipment

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm the specific suffix 'GJ6' matches the required TSOT-23-6 package variant. Check RoHS compliance status and moisture sensitivity level (MSL 3) requirements against assembly process capabilities. Ensure the part number corresponds to the exact electrical specifications needed for the target application.

Selection Notes

Select this component when a small form factor is required for driving single-string white LEDs. Consider the 400mA output limit and 1MHz frequency for compatibility with passive components. Evaluate the 2.7V minimum input voltage against the system's power source. Compare against alternative drivers if higher current capacity or different topologies are necessary for the specific load requirements.

Part Context
