www.DataSheet.co.kr fitipower integrated technology lnc. FP6321 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 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 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 eliminates the need for a current sensing resistor. This device is available in SOP-8 package. Features ● Operates from +5V or +12V ● Drives Two Low Cost N-Channel MOSFETs ● Fast Transient Response ● Simple Single-Loop Control Design ( Voltage-Mode PWM Control) ● Internal Soft-Start ● Over-C […]
