23V, 3A, 380KHz Asynchronous Step-Do8w5Tn
DC/DC Converter
Description
The FR9723B is a 380KHz step-down DC/DC converter that provides wide 4.75V to 23V input voltage range and 3A continuous load current capability.
Fault protection includes cycle-by-cycle current limit, input UVLO and thermal shutdown. Besides, adjustable soft-start function prevents inrush current at turn-on. This device uses current mode control scheme that provides fast transient response. In shutdown mode, the supply current is about 10μA.
The FR9723B is available in an 8-pin SOIC package, which provides a very pact system solution and good thermal conductance.
