DiodesZetex, AC-DC Converter, 3.3 → 20 V dc 6-Pin, SOT-26 APR348W6-7

The DiodesZetex 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 configure into high-side or low-side application to fit various design requirement. It also has specialized light load mode and determines safe driver pulse generation through load detection. The VDD power supply can be charged by VDET or VCC, which means it can be charged by internal PLR (Pulse linear regulator) at low output voltage and charged by internal LDO at high output voltage. Therefore, it can provide a wide output operation voltage from 3.3V to 20V. The APR348 is available in SOT26 (Type CJ) package.
