Descripción detallada

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 very fast turn-on and turn-off delay to reduce power loss and keep safe operation without adding any external components or circuitry. The APR348 can configure into high-side or low-side application to fit various design needs, and it can also provide highperformance solutions up to 20V output voltage application. APR348 detects load conditions and determines safe pulse generation at light loads. The APR348 power supply can be charged by VDET or VCC, depending on PLR voltage from VCC pin, and can provide a wide output operation voltage to 20V.

The APR348 is available in SOT26 (Type CJ) package.
