MP4601ES-LF-P

Overview

The MP4601ES-LF-P is a partial power white LED driver IC designed for television applications. It utilizes a Buck-Boost topology to manage high-voltage inputs ranging from 4.5 V to 75 V. The device supports analog and PWM dimming methods for precise brightness control. It operates at a switching frequency of 950 kHz and delivers output current through a single channel. The component is housed in an SOIC-16 package with a bare pad for thermal management.

Feature Summary

• Integrates a Buck-Boost converter topology suitable for wide input voltage ranges in TV backlighting systems.
• Supports both analog and pulse-width modulation (PWM) dimming techniques for flexible brightness adjustment.

Applications

• White LED drivers for television displays
• Partial power LED lighting solutions

Procurement Notes

Verify the specific suffix 'P' against official Monolithic Power Systems documentation, as standard listings may indicate 'Tube' packaging while this variant implies reel configuration. Confirm RoHS compliance status and moisture sensitivity level details directly from the manufacturer's datasheet before finalizing procurement plans.

Selection Notes

Select this component for designs requiring a single-channel Buck-Boost LED driver capable of handling up to 75 V input. Ensure the application environment remains within the specified -20°C to +85°C operating temperature range. Consider that the part is marked as obsolete or not recommended for new designs by some distributors; verify current availability and potential obsolescence risks prior to integration.
