RT9293BGJ6

Overview

The RT9293BGJ6 is a high-frequency asynchronous boost LED constant current driver controller manufactured by Richtek USA Inc. It operates at a switching frequency of 1MHz, enabling the use of compact external components to simplify electromagnetic interference (EMI) management. The device integrates an internal MOSFET capable of supporting up to ten series-connected white LEDs for backlight applications and OLED power supplies. It features built-in soft-start functionality to eliminate inrush current during startup. The controller supports PWM dimming via the Enable pin or feedback network, allowing precise control of output current and backlight intensity.

Feature Summary

Integrates an internal MOSFET suitable for driving multiple series-connected white LEDs
Supports PWM dimming control through the Enable pin or feedback voltage adjustment
Includes soft-start circuitry to prevent inrush current during initialization

Applications

LCD backlight LED drivers
OLED power supply circuits
LCD bias voltage generation

Procurement Notes

Verify component authenticity against manufacturer documentation due to discontinuation status. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Cross-reference ordering information with official Richtek EOL notices to ensure compatibility with existing production schedules and replacement strategies.

Selection Notes

Select this controller for designs requiring high-frequency operation to minimize passive component size. Ensure input voltage ranges align with the boost topology requirements. Verify that the external current sense resistor values match the desired LED drive current specifications. Consider thermal dissipation capabilities when designing for high-density PCB layouts.

Part Context

This component belongs to the RT9293 family of power management ICs designed for display backlighting. It complements other Richtek solutions like the RT9285 and RT9296 by offering a dedicated asynchronous boost architecture optimized for white LED strings. The BGJ6 suffix indicates a specific surface-mount package variant within the broader product line.
