MP4652ES-LF-P

Overview

The MP4652ES-LF-P is an offline LED lighting driver IC designed for white LED applications in large televisions. It utilizes a flyback topology to drive a single output channel with a maximum current of 2 A. The device operates within an input voltage range of 9 V to 30 V and features a fixed switching frequency of 50 kHz. It is housed in a SOIC-16 package and supports surface-mount installation. The component functions reliably across a temperature range of -20°C to +85°C, with a maximum power dissipation of 1.56 W.

Feature Summary

• Integrates flyback converter topology for efficient offline power conversion
• Supports PWM dimming control for precise brightness adjustment
• Includes thermal protection mechanisms for enhanced operational safety

Applications

• White LED backlighting for large television displays
• Offline LED lighting systems requiring single-channel regulation
• General-purpose LED driver circuits utilizing flyback architecture

Procurement Notes

Verify the specific suffix designation when ordering, as the 'P' variant indicates tape-and-reel packaging. Confirm that the design accommodates the specified 9 V to 30 V input range and 50 kHz switching frequency. Ensure the application environment remains within the -20°C to +85°C operating temperature limits to maintain performance reliability.

Selection Notes

Select this component for designs requiring a dedicated offline flyback controller for large TV backlights. Consider the 2 A output current capability and SOIC-16 footprint for PCB layout constraints. Evaluate compatibility with existing PWM dimming signals and verify that the thermal management strategy supports the 1.56 W power dissipation rating under worst-case conditions.
