The W83323G is a high-speed, N-Channel synchronous buck regulator controller. The W83323G employs fixed-frequency voltage-mode PWM control architecture. Both high-side and low-side MOSFETs are lower cost N-Channel type. 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 a local charge pump. Besides, the current limit is achieved by monitoring the voltage drop across the on resistance of the low-side MOSFET. This method eliminates the requirement of extra current sensing resistor and avoids false trigger of OC protection when VIN varies. (Source: www.chipcatalog.com)
