RT8450BGCP

Overview

The RT8450BGCP is a high-voltage multi-topology LED driver IC manufactured by Richtek USA Inc. It functions as a current mode PWM regulator designed for LED driving applications. The device integrates an internal 1.5A power switch and supports wide input voltage ranges from 4.5V to 40V, with output capabilities up to 50V. This architecture allows the component to operate in Buck, Boost, or Buck-Boost topologies. It is housed in a 16-pin TSSOP EP package.

Feature Summary

Supports Buck, Boost, and Buck-Boost operational topologies
Integrates an onboard 1.5A power switch
Enables PWM to analog dimming control

Applications

LED backlighting systems
General LED lighting solutions

Procurement Notes

Verify the specific suffix BGCP against the official datasheet to confirm pinout and thermal pad configuration. Ensure compatibility with the intended topology (Buck, Boost, or Buck-Boost) regarding input and output voltage requirements. Confirm availability status as distribution data may vary.

Selection Notes

Select this component when a single IC must support multiple converter topologies for flexible LED drive designs. The integrated 1.5A switch simplifies external component count compared to controller-only solutions. Verify that the required input and output voltage ranges fall within the specified 4.5V-40V and 50V limits respectively.

Part Context

This part belongs to the RT8450 series of high-voltage LED drivers. It is distinct from non-integrated controllers like the RT8477A and lower-current variants like the RT8453B. The BGCP designation indicates a specific package variant within the broader family of multi-topology regulators.
