WT7140BC

AC/DC切換穩(wěn)壓器; ? Secondary side controller optimized for USB PD \n? Built-in 100V/5.8mΩ (Typ.) MOSFET\n? Low startup current\n? Suitable for flyback CCM/DCM/QR/Valley switching operation\n? No need the auxiliary winding\n? Unique dynamic DRV control technology for fast turn off\n? Outline package (Green Package): SPPAK;

The WT7140BC is a high-performance synchronous rectification controller with an integrated 100V MOSFET. It can replace a diode rectifier in a flyback switch mode power supply. Without external auxiliary winding supplies, the WT7140BC can easily provide power to the VDD. It can be powered by D and VD pin. The WT7140BC built-in several circuits to minimize external part counts and overall total system cost. By sensing the voltage across the conduction resistance of MOSFET, the controller can determine the turn-on/turn-off timing of the internal driver to achieve the lowest loss and high speed sensing. Due to the WT7140BC built-in 100V MOSFET, the WT7140BC is suitable for high output current and wide output voltage range application (e.g., PD3.0 and PPS, from 5V to 21V).
