MP8756GD-Z

Voltage Regulators - DC DC Switching Regulators Overview

The MP8756GD-Z is a synchronous step-down DC-DC converter manufactured by Monolithic Power Systems. It operates with an input voltage range of 4.5V to 26V and provides a single adjustable output from 0.6V to 5.5V. The device delivers a continuous output current of 6A at a fixed switching frequency of 700kHz. It utilizes adaptive constant on-time control for fast transient response. The component is housed in a compact 12-PowerVFQFN package, measuring 2x3mm, and supports junction temperatures from -40°C to 125°C.
