MP4601ES-LF

Overview

The MP4601ES-LF-Z is a monolithic LED lighting driver IC designed for partial power White LED applications in TV systems. It integrates Boost and Buck topologies within a single SOIC-16 package. The device operates on an input voltage range of 4.5 V to 75 V with a fixed switching frequency of 950 kHz. It supports one output channel and features both analog and PWM dimming capabilities. The component functions within a temperature range of -20°C to +85°C, drawing a maximum supply current of 1 mA.

Feature Summary

Integrates combined Boost and Buck converter topologies for efficient LED driving
Supports dual-mode dimming via analog control and Pulse Width Modulation (PWM) signals
Designed specifically for partial power architectures in television displays

Applications

White LED drivers for television panels
Partial power LED backlighting systems
TV display module illumination circuits

Procurement Notes

Verify the Not Recommended for New Design (NRND) status before finalizing any schematic or procurement plans. Confirm that the specific suffix LF-Z aligns with required lead-free and RoHS compliance standards. Ensure the SOIC-16 package dimensions match the target PCB footprint constraints. Validate that the 950 kHz switching frequency does not conflict with existing electromagnetic interference requirements in the system design.

Selection Notes

Select this component when designing partial power LED driver stages for television applications requiring integrated boost and buck functionality. The wide input voltage range accommodates various bus voltages common in TV power supplies. Consider the single-channel output limitation and the specific operating temperature range of -20°C to +85°C against environmental requirements. Verify compatibility with analog and PWM dimming interfaces used in the host system.

Part Context

This part belongs to the MP4601 series of LED lighting driver ICs manufactured by Monolithic Power Systems. It is categorized under LED Lighting Drivers and Driver ICs. The manufacturer identifies it as a specialized solution for white LEDs, distinct from general-purpose DC-DC converters found in other product lines like the MP2149 or MP2361 series.
