FP6326/A Synchronous Buck PWM DC-DC Controller Description The FP6326/A 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 or 600kHz frequency provides simple, single feedback loop, voltage mode control with fast transient response.
The resulting PWM duty ratio ranges from 0-100%.
The FP6326/A 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.
