MP23701GQEU-P

LED Driver IC Overview

The MP23701GQEU-P is a monolithic synchronous step-down white LED driver from Monolithic Power Systems. It operates with an input voltage range of 4.2 V to 24 V and delivers up to 2 A output current. The device integrates a 100 mΩ high-side power MOSFET and an 80 mΩ low-side synchronous rectifier, achieving efficiencies up to 97%. It functions at a fixed switching frequency of 1.5 MHz and utilizes a 100 mV feedback reference voltage. Packaged in an 8-pin UTQFN, it supports surface mount installation and operates within a temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Integrates high-side and low-side power MOSFETs for compact synchronous buck topology
• Provides short circuit and thermal protection mechanisms
• Supports auto-restart functionality upon fault clearance

LED Driver IC Applications

• High-power LED lighting systems
• LED backlighting applications
• General-purpose DC-DC conversion for LED loads

LED Driver IC Procurement Notes

Verify the specific suffix 'P' indicates Cut Tape or MouseReel packaging rather than standard Reel quantities. Confirm RoHS compliance status through official datasheets. Ensure design compatibility with the 1.5 MHz switching frequency and 100 mV feedback threshold. Validate that the UTQFN-8 package dimensions meet PCB layout requirements.

LED Driver IC Selection Notes

Select this component when a single-channel synchronous buck driver is required for white LEDs. It is suitable for designs needing input voltages up to 24 V and output currents up to 2 A. Consider the 1.5 MHz frequency for smaller passive components compared to lower-frequency alternatives. Verify thermal performance requirements given the integrated MOSFET structure.
