IR3894MTR1PBF

Voltage Regulators - DC DC Switching Regulators Overview

The IR3894MTR1PBF is a dual-channel synchronous buck regulator from Infineon's SupIRBuck family. It integrates two independent channels, each delivering up to 6A of output current. The device supports an input voltage range from 2.5V to 21V and provides adjustable output voltages between 0.6V and 12V. Operating with a fixed switching frequency of 300kHz, it utilizes a PQFN-32 package for compact surface-mount implementation. This component is designed for high-efficiency power conversion in data processing systems.
