FP6321A - Fiti

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 simple, single feedback loop, voltage mode control with fast tr.

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
