Voltage Regulators - DC DC Switching Regulators datasheet and documents for MP2452DD-LF-P

MP2452DD-LF-P

Voltage Regulators - DC DC Switching Regulators Overview

The MP2452DD-LF-P is a Monolithic Power Systems buck switching regulator IC in an 8-QFN (2x3mm) package. It operates with an input voltage range of 3.3V to 36V and provides a single adjustable output from 0.794V to 33V at up to 1A. The device features a fixed 1MHz switching frequency, 230µA operating quiescent current, and less than 1µA shutdown current. It includes internal compensation, soft start, thermal shutdown, and frequency foldback for stable operation.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a high-voltage power MOSFET for efficient step-down conversion
Adjustable output voltage via external resistor divider
Includes protection mechanisms such as thermal shutdown and frequency foldback

Voltage Regulators - DC DC Switching Regulators Applications

Automotive electronics requiring wide input voltage tolerance
Battery-powered devices utilizing low shutdown current
General-purpose DC-DC step-down power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'LF-P' corresponds to the lead-free tape-and-reel packaging configuration. Confirm that the 8-TFDFN bare pad footprint matches your PCB layout requirements. Ensure compatibility with ceramic output capacitors as specified for stability. Cross-reference the manufacturer datasheet for exact mechanical dimensions and soldering recommendations before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a non-synchronous buck converter is required for 1A loads within a 36V input limit. The absence of synchronous rectification distinguishes it from similar MPS models like the MP2457. Consider the 1MHz frequency for balancing efficiency and passive component size. Verify that the 230µA quiescent current meets system standby requirements compared to lower-power alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MP2452 family of high-frequency buck converters. It shares core specifications with variants like the MP2452DD-LF-Z, differing primarily in packaging format. The device is designed for applications needing robust performance across automotive and industrial temperature ranges while maintaining a compact physical profile.
