APR3415MTR-G1

Overview

The APR3415MTR-G1 is a secondary side synchronous rectifier controller manufactured by Diodes Incorporated. Designed for flyback AC/DC converter topologies, it integrates an N-channel MOSFET to replace traditional diodes, thereby reducing conduction losses and improving overall power supply efficiency. The device operates within a supply voltage range of 3.3V to 6V and draws a typical operating supply current of 100 µA. It supports output voltages up to 5V and functions reliably across an extended temperature range from -40°C to +85°C. Packaged in an 8-SOIC surface-mount format, this component facilitates compact designs while maintaining high performance standards.
