FR9882
18V, 2A, 340KHz Synchronous Step-Down
DC/DC Converter
Description
The FR9882 is a synchronous step-down DC/DC
converter that provides wide 4.5V to 18V input
voltage range and 2A continuous load current
capability.
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 that
provides fast transient response. In shutdown mode,
the supply current is about 10uA.
The FR9882 is available in an 8-pin SOIC package,
provides a very compact system solution and good
thermal conductance.
