MP4655GY-P

Overview

The MP4655GY-P is a single-stage LLC LED current and system voltage controller designed for large LCD TV backlighting. It operates within an input voltage range of 9 V to 35 V and supports a switching frequency from 20 kHz to 350 kHz. The device provides one output channel with a maximum output current of 1 A. It is housed in a SOIC-28 package and functions reliably across a temperature range of -40°C to +125°C, with a maximum power dissipation of 2.1 W.

Feature Summary

Integrates pure single-stage LLC control for simultaneous LED current regulation and system voltage management
Supports analog dimming capabilities for precise brightness adjustment
Includes comprehensive protection mechanisms such as thermal shutdown and overload protection

Applications

Large LCD TV backlighting systems
LED lighting drivers requiring integrated voltage and current control
Single-channel high-efficiency LED power supplies

Procurement Notes

Verify the specific suffix against official Monolithic Power Systems documentation to confirm pinout compatibility and environmental compliance status. Ensure that the SOIC-28 package dimensions align with your PCB footprint requirements. Confirm moisture sensitivity level handling procedures during assembly to prevent damage. Cross-reference the latest datasheet revision for any updates on recommended operating conditions or testing parameters.

Selection Notes

Select this component when designing single-stage converters for large displays requiring combined voltage and current regulation. The wide input voltage range suits various AC-DC conversion topologies. Consider the SOIC-28 package for adequate thermal performance given the 2.1 W dissipation rating. Evaluate the 350 kHz maximum frequency for transformer size optimization versus EMI constraints.

Part Context
