MP6902DS-LF-Z

Power Supply Controllers, Monitors Overview

The MP6902DS-LF-Z is a flyback switching controller designed for secondary-side synchronous rectification. It operates at a maximum switching frequency of 400 kHz and supports isolated topologies with one output. The device functions within an operating temperature range of -40°C to +125°C and requires a supply voltage of 12 V, drawing 8 mA of operating current. It is housed in an SOIC-8 surface-mount package and includes shutdown functionality.

Power Supply Controllers, Monitors Feature Summary
