RT9361BGE

Overview

The RT9361BGE is a high-performance regulated charge pump DC/DC converter manufactured by Richtek USA Inc. It operates as an LED driver IC with one output, delivering up to 150mA at a regulated 4.5V or 5V output voltage. The device utilizes a switching capacitor topology and supports PWM dimming for brightness control. It functions within a supply voltage range of 2.8V to 5V and includes internal switches, eliminating the need for external inductors. The component is housed in a compact SOT-23-6 package and is designed for surface-mount installation.

Feature Summary

Regulated charge pump topology providing stable 4.5V or 5V output without external inductors
Integrated PWM dimming capability for precise LED brightness control
Compact SOT-23-6 surface-mount package suitable for space-constrained designs

Applications

LED backlighting systems
Camera flash drivers

Procurement Notes

Verify the exact suffix 'BGE' against official Richtek documentation, as primary datasheets often reference RT9361A/B variants. Confirm package type compatibility, noting that some sources list WDFN EP for the B variant while others cite SOT-23-6. Check end-of-life status and lead times through authorized distributors, as availability may be limited due to product lifecycle changes.

Selection Notes

Select this component when a small form factor charge pump is required for driving LEDs with regulated current. Ensure the input voltage remains above 3.2V for optimal performance as specified in typical application notes. Consider the 150mA output limit and PWM dimming interface requirements during circuit design. Verify thermal management needs given the SOT-23-6 package constraints.

Part Context

The RT9361 series belongs to Richtek's portfolio of PMIC solutions focused on portable electronics. It complements other LED drivers like the RT9300AGE but differs by using a charge pump rather than linear regulation. This allows higher efficiency in specific voltage conversion scenarios common in mobile devices and camera modules where inductor space is restricted.
