IR3827MTRPBF

Voltage Regulators - DC DC Switching Regulators Overview

The IR3827MTRPBF is a synchronous buck switching regulator IC from Infineon Technologies, part of the SupIRBuck series. It delivers an adjustable output voltage ranging from 0.6V to 18.06V with a maximum continuous output current of 6A. The device operates within an input voltage range of 5.5V to 21V and supports programmable switching frequencies between 300kHz and 1.2MHz. Housed in a compact 17-PowerVQFN package (4x5mm), it functions as a single-output positive regulator designed for surface-mount installation across an industrial temperature range of -40°C to 125°C.
