APR348W6-7 MOSFET Driver

Diodes' APR348W6-7 is a secondary-side MOSFET driver for synchronous rectification, which can reduce the secondary-side rectifier power dissipation and provide a high-performance solution. It can support continuous conduction mode (CCM) or discontinuous conduction mode (DCM) and quasi-resonant (QR) flyback operation based on a MOSFET operating on-time control technology. This technology provides fast turn-on and turn-off delay to reduce power loss and keep a safe operation without adding any external components or circuitry. The APR348W6-7 can configure into high-side or low-side applications to fit various design needs. It can provide high-performance solutions up to 20 V output voltage application. This device detects load conditions and determines safe pulse generation at light loads and the power supply can be charged by V_DET or V_CC, depending on PLR voltage from the V_CC pin, and provides a wide output operating voltage to 20 V, all in a SOT26 package type.
