RT9302GJ8

Overview

The RT9302GJ8 is a 60mA, 3-channel pulse dimming current source LED driver manufactured by Richtek USA Inc. It operates with a supply voltage range of 2.8V to 5.5V and delivers an output current of 20mA per channel. The device supports PWM dimming and functions at a frequency of 1MHz. Designed for surface mount installation in TSOT-23-8 packages, it ensures reliable performance across an operating temperature range of -40°C to 85°C.

Feature Summary

Provides three independent current channels for precise LED control
Supports pulse dimming functionality for efficient brightness adjustment
Integrates internal switching components within a compact surface-mount package

Applications

Backlight illumination systems
Portable electronic display modules
Compact lighting arrays requiring multi-channel regulation

Procurement Notes

Verify the specific suffix GJ8 against official Richtek documentation to confirm package type and thermal characteristics. Ensure compatibility with system voltage limits of 2.8V minimum and 5.5V maximum. Confirm that the 1MHz switching frequency aligns with electromagnetic interference requirements for the target application environment.

Selection Notes

Select this component when a compact solution for three-channel LED driving is required. The TSOT-23-8 package suits space-constrained designs. Verify that the 60mA total current capability meets load requirements without exceeding per-channel limits. Consider the PWM dimming interface for integration with existing control logic.

Part Context

This IC belongs to the Richtek LED driver family, focusing on low-power, multi-channel applications. It addresses the need for efficient backlighting in portable devices where size and power consumption are critical constraints. The design emphasizes simplicity and reliability for standard consumer electronics.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Consult manufacturer resources for direct equivalents if availability is constrained.
