MPX2002
All-in-One Flyback Controller with Integrated
Primary Control Circuitry and Secondary
Synchronous Rectification Driver
DESCRIPTION
The MPX2002 is an all-in-one flyback controller with an integrated primary driving circuit, secondary controller, synchronous rectification driver, and safety-compliant feedback. It offers the benefits of both primary-side regulation (PSR) and secondary-side regulation (SSR).
A feedback circuit is not required, which reduces system complexity and the total BOM cost. The synchronous rectifier (SR) can match the driving signal of the primary-side MOSFET, meaning the SR can operate safely in continuous conduction mode (CCM).
