RT9288AGE

Overview

The RT9288AGE is a DC-DC controller IC manufactured by Richtek USA Inc., designed for LED driver applications. It operates as a boost topology converter with PWM dimming capability and supports a single output. The device functions within a supply voltage range of 3V to 13.5V and switches at a frequency of 1MHz. It lacks an internal switch and utilizes a SOT-23-6 surface-mount package. The component is rated for operation between -40°C and 85°C ambient temperature.

Feature Summary

Supports PWM dimming control for LED brightness adjustment
Boost topology configuration for step-up voltage conversion
Single output channel design for dedicated load driving

Applications

LED backlight systems
Portable electronic display illumination
General LED lighting circuits

Procurement Notes

Verify the current lifecycle status before procurement, as official records indicate this product has reached end-of-life (EOL) with specific termination dates in September 2025 and November 2026. Confirm availability through authorized distributors or secondary markets, as standard manufacturing may have ceased. Ensure compatibility with existing board designs when sourcing replacement units from alternative suppliers.

Selection Notes

Select this component for applications requiring a compact boost controller without integrated power switches. The SOT-23-6 package suits space-constrained designs. Verify that the external inductor and diode selection aligns with the 1MHz switching frequency. Consider the absence of internal protection features inherent to controller-only ICs when designing the surrounding circuitry.
