FR9723B 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 compact system solution and good thermal conductance.
Features ● Wide Input Voltage from 4.
75V to 23V ● 3A Output Current ● Adjustable Output Voltage from 1.
23V to 20V ● 100mΩ Integrated Power MOSFET ● High Efficiency up to 90% ● Fixed 380KHz Switching Frequency ● Current Mode Operation ● Adjustable Soft-Start ● Cycle-by-Cycle Current Limit...
