N-channel Fet Synchronous Buck Regulator Controller

The W83320S is a high-speed, N-Channel synchronous buck Regulator controller optimized for wide reference input range. The W83320S employs adjustable frequency ranging from 100 KHz to 400 KHz voltage-mode PWM control architecture. The Regulator is biased from a 5V rail and the power for the high-side MOSFET CAN be supplied by a separate 12V rail or supplied from the internal Charge Pump A Current limit protection is implemented by monitoring the voltage drop across the Switch ON resistance of the low-side MOSFET This method CAN eliminate the requirement of extra current sensing resistor and avoids false trigger of OC protection when VIN varies efficiently. The adaptive non-overlapping MOSFET Gate drivers help avoid potential shoot-through problems while maintaining high efficiency. All these together with Power-good flag, enable and soft start features make power sequencing easy. By Winbond Electronics Corp America
