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. Features ● Wide Input Voltage from 4.
