SECONDARY SIDE SYNCHRONOUS RECTIFICATION CONTROLLER
Description
The APR348 is a secondary-side MOSFET driver for synchronous rectification, which can effectively reduce the secondary-side rectifier power dissipation and provide a high-performance solution.

The APR348 can support continuous or discontinuous conduction mode (CCM and DCM) and quasi-resonant flyback operation based on a MOSFET operating on-time control technology. This technology provides minimized turn-on and turn-off delay to reduce power loss and keep safe operation without adding any external ponents or circuitry.
