Part No.	W83320G
Datasheet	W83320G.pdf
Description	The W83320G is a high-speed, N-Channel synchronous buck regulator controller optimized for wide reference input range. The W83320G 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.
Features	0.8V to 5V power stage input voltage Providing +/-1.5% reference voltage Power Good flag Voltage-Mode PWM Control Fast Transient Response Soft Start Switching frequency from 100kHz to 400kHz
