MP4601EF-LF

Overview

The MP4601EF-LF-Z is a partial power WLED driver IC for TV applications, manufactured by Monolithic Power Systems. It features boost and buck topologies with a TSSOP-EP-16 package. The device operates on a supply voltage range of 4.5 V to 75 V at a switching frequency of 950 kHz. It supports analog and PWM dimming methods. The component is rated for operation between -20°C and +85°C. It provides one output channel with a switch current capacity of 2.5 A. The part is classified as NRND (Not Recommended for New Designs).

Feature Summary

Integrates boost and buck converter topologies for flexible LED drive configurations.
Supports both analog and pulse-width modulation (PWM) dimming control methods.
Configurable output current from 20 mA to 150 mA using external resistors without microcontroller intervention.

Applications

TV backlight systems
Automotive lighting
Partial power WLED drivers

Procurement Notes

Verify the NRND status before integration, as this indicates the component is not recommended for new designs. Confirm the specific suffix (LF-Z) matches the required RoHS compliance and tape-and-reel packaging specifications. Ensure the TSSOP-EP-16 footprint aligns with existing PCB layouts. Cross-reference the latest datasheet for any pinout or electrical characteristic updates prior to finalizing procurement orders.

Selection Notes

Select this component when designing partial power WLED drivers requiring integrated boost and buck capabilities. It is suitable for applications needing configurable output currents between 20 mA and 150 mA via external resistors. Consider the 950 kHz switching frequency and 75 V maximum supply voltage limits. Verify compatibility with analog and PWM dimming requirements for the target display system.

Part Context

This part belongs to the MP4601 series of LED driver ICs from Monolithic Power Systems. It is designed specifically for white LED backlighting in television sets. The device integrates power switches and control logic to simplify the design of efficient LED driving circuits. It replaces discrete solutions by combining multiple functions into a single monolithic chip.
