FP6321 Datasheet | Fitipower

.DataSheet.co.kr fitipower integrated technology lnc. Synchronous Buck PWM DC-DC Controller Description The FP6321 is designed to drive two N-channel MOSFETs in a synchronous rectified buck topology. It provides the output adjustment, internal soft-start, frequency pensation 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 transient response. The resulting PWM duty ratio ranges from 0-100%. The FP6321 Features over current protection. The output current is monitored by sensing the voltage drop across the RDS-ON of the low side MOSFET which...
