MP2456GJ-P

Voltage Regulators - DC DC Switching Regulators Overview

The MP2456GJ-P is a monolithic step-down switching regulator from Monolithic Power Systems, housed in a TSOT-23-6 package. It integrates a power MOSFET to deliver a peak output current of 0.5A with excellent load and line regulation across a wide input voltage range of 4.5V to 50V. Operating at a fixed frequency of 1.2MHz, the device utilizes current-mode control for fast transient response and loop stability. The adjustable output voltage ranges from 0.81V to 0.9 times the input voltage. Key protection features include cycle-by-cycle overcurrent limiting and thermal shutdown.
