Product details

Overview

MP4255GVE-0000-P from Monolithic Power Systems is a 36V dual-channel synchronous buck converter with an integrated 6V LDO output. The device is designed for automotive, industrial, and distributed power systems that need two adjustable 3A buck rails and a small auxiliary LDO rail from a 4V to 36V input.

As part of the MP4255 product family, MP4255GVE-0000-P combines two synchronous step-down regulators, integrated power MOSFETs, configurable OTP settings, a 6V LDO output, selectable switching frequencies, frequency spread-spectrum options, protection functions, and a wettable-flank 21-QFN package. For engineers reviewing the MP4255GVE-0000-P datasheet, MP4255GVE-0000-P pinout, MP4255GVE-0000-P application, or MP4255GVE-0000-P equivalent, this device is widely used in automotive modules, industrial controllers, distributed power rails, infotainment systems, sensor hubs, and compact dual-rail embedded power architectures.

Technical Context

In vehicle and industrial power systems, MP4255GVE-0000-P operates as a dual-channel buck regulator. Each synchronous channel can generate an adjustable output from a 4V to 36V input, supporting local 3A rails for processors, sensors, communication ICs, or peripheral loads.

The integrated 6V LDO can provide a low-current bias rail, and the OTP configuration defines default functions such as switching frequency, I2C address, slew-rate behavior, spread-spectrum enable, LDO voltage, and thermal thresholds.

MP4255GVE-0000-P is commonly used when wettable-flank QFN inspection, dual buck conversion, wide input support, configurable defaults, and compact 4mm x 5mm packaging are required.

Equivalent & Alternatives

When evaluating a MP4255GVE-0000-P equivalent, engineers should compare input range, dual buck current, LDO function, OTP configuration, switching frequency, package, and wettable-flank requirements.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MPQ4423AGQ-AEC1	MPS automotive buck regulator with different single-output architecture.	Used in vehicle point-of-load rails.	Compare rail count, current, package, and qualification.
LT8645S	Analog Devices high-current synchronous buck regulator with different single-output integration.	Used in automotive and industrial rails.	Compare dual-output need, LDO function, current, and package.

Compared with MPQ4423AGQ-AEC1, MP4255GVE-0000-P integrates two buck channels and an LDO in one PMIC. MP4255GVE-0000-P vs LT8645S selection depends on whether the design needs dual outputs, OTP defaults, wettable-flank package, and integrated bias support.

Quality

MP4255GVE-0000-P should be sourced as original Monolithic Power Systems components through traceable supply channels. Quality checks may include wettable-flank QFN inspection, top-mark validation, solderability testing, dual buck output verification, LDO output testing, and OTP configuration review.

Production validation should include load transients, thermal behavior, switching frequency, spread-spectrum setting, fault behavior, and output-voltage accuracy.
