FR9833

3A, 32V Car Charger / Adapter Synchronous Step-Down Converter

 

General Description   

The FP9833 is a buck regulator with a built in internal power MOSFET. It achieves 3A continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. Internal compensation function reduces external compensation components and simplifies the design process. Its fault protection includes cycle-by-cycle current limit, input UVLO, output over voltage protection and thermal shutdown. Besides, adjustable soft-start function prevents inrush current at turn-on.
