IR3883MTRPBF Infineon DC-DC Converter | 16-PQFN(3X3) | 6A, 2.5V-14V Input

Product Overview

The IR3883MTRPBF from Infineon is a high-efficiency, synchronous buck DC-DC converter capable of delivering up to 6A of continuous output current. It operates from an input voltage range of 2.5V to 14V and provides an adjustable output voltage down to 0.5V. Housed in a compact 16-PQFN (3x3mm) package, this device integrates both high-side and low-side MOSFETs, minimizing external component count and board space. The IR3883MTRPBF features a fixed 600kHz switching frequency, enabling a good balance between efficiency and solution size. It includes comprehensive protection features such as overcurrent protection (OCP), overvoltage protection (OVP), undervoltage lockout (UVLO), and thermal shutdown. The device is designed for a wide range of applications requiring high power density and reliable performance.
