21V, 2A, 600KHz Synchronous Step-Dow85nT DC/DC Converter
Description
The FR9801 is a synchronous step-down DC/DC converter that provides wide 4.5V to 21V input voltage range and 2A continuous load current capability.
The FR9801 fault protection includes cycle-by-cycle current limit, UVLO, output overvoltage protection and thermal shutdown. The adjustable soft-start function prevents inrush current at turn-on. This device uses current mode control scheme which provides fast transient response. Internal pensation function reduces external pensation ponents and simplifies the design process. In shutdown mode, the supply current is less...
