FP6321A Sunchronous Buck PWM DC-DC Controller

The FP6321A is designed to drive two N-channel MOSFETs in a synchronous rectified buck topology. It provides the output adjustment, internal soft-start, frequency compensation networks, monitoring and protection functions into a single package. The IC operating at fixed 300kHz frequency provides sim.

FP6321A Features

* over current protection. The output current is monitored by sensing the voltage drop across the RDS (ON) of the low side MOSFET which eliminates the need for a current sensing resistor. This device is available in SOP-8 package. Pin Assignment SO Package (SOP-8) Features

* Operates from +5V or
