MP6902DS-LF

Power Supply Controllers, Monitors Overview

The MP6902DS-LF is a flyback switching controller designed for secondary-side synchronous rectification. It operates with a maximum switching frequency of 400 kHz and supports a duty cycle up to 50%. The device regulates the forward voltage drop of an external MOSFET to approximately 70mV, replacing Schottky diodes to improve efficiency. It functions within a supply voltage range of 8V to 24V and draws 8 mA of operating current. The component is rated for an output voltage of 15 V and an output current of 8 mA. It operates reliably between -40°C and +125°C in an SOIC-8 package.
