FR9888 23V, 3.5A, 340KHz Synchronous Step-Down DC/DC Converter

SKU: 20193821

In stock


SMD-8 - The FR9888 is a synchronous step-down DC/DC
converter that provides wide 4.5V to 23V input
voltage range and 3.5A continuous load current
The FR9888 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. This device uses current mode control
scheme which provides fast transient response.
Internal Compensation function reduces external
compensation components and simplifies the design
process. In shutdown mode, the supply current is
less than 1?A.
The FR9888 is available in an 8-pin SOIC package,
provides a very compact system solution and good
thermal conductance.
