MP4651ES-LF-P

Overview

The MP4651ES-LF-P is an LED lighting driver IC from Monolithic Power Systems, designed for offline half-bridge LLC WLED controller applications. It features a single output capable of delivering up to 2 A of current. The device operates within an input voltage range of 9 V to 30 V and supports a switching frequency of 50 kHz. Packaged in a SOIC-16 format with SMD/SMT installation style, it functions reliably between -20°C and +85°C. The component includes PWM dimming capabilities and has a maximum power dissipation of 2.5 W.

Feature Summary

Supports offline half-bridge LLC topology for WLED control
Integrates PWM dimming functionality for brightness adjustment
Provides single-channel high-current LED drive capability

Applications

WLED backlighting systems
Offline LED lighting drivers
General LED illumination circuits

Procurement Notes

Verify the NRND status before integration, as this component is not recommended for new designs. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Cross-reference the specific suffix 'P' for reel packaging details against official MPS documentation to ensure compatibility with automated assembly processes.

Selection Notes

Select this component only for legacy or existing design maintenance where the NRND status does not impact long-term supply chain stability. Evaluate thermal management requirements carefully due to the 2.5 W power dissipation limit in the SOIC-16 package. Ensure the application strictly utilizes the specified 9 V to 30 V input range and 50 kHz operating frequency constraints.

Part Context

This part belongs to the MP4651 series of LED lighting driver ICs manufactured by Monolithic Power Systems. It serves as an offline controller specifically optimized for half-bridge LLC resonant converters used in white LED applications. The ES variant denotes the specific temperature grade and package configuration within the broader product family.
