APR348
SECONDARY SIDE SYNCHRONOUS RECTIFICATION CONTROLLER Description Pin Assignments NEW PRODUCT 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. (Top View) 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. VCC 1 6 VDET GND 2 5 DRISR Rx 3 4 VDD SOT26 (Type CJ) The APR348 is available in SOT26 (Type CJ) package. Features Applications Synchronous Rectification Controller
