MB39C022GPN-G-ERE1

Overview

The MB39C022GPN-G-ERE1 is a single-output synchronous buck DC/DC converter manufactured by Infineon Technologies. It operates within an input voltage range of 2.5 V to 5.5 V and provides a fixed output voltage of 3.3 V with a maximum load current of 300 mA. The device integrates a high-frequency switching controller operating at 2 MHz, enabling the use of compact external components. Packaged in a thermally enhanced SON-EP-10 surface-mount footprint, it supports operation across an industrial temperature range from -40 °C to +85 °C. Key functional features include a dedicated shutdown pin for power management and low noise performance suitable for sensitive analog circuits.
