FR9888 详细介绍

FR9888概述:3A, 23V, 340kHz同步整流降压DC-DC
The FR9888 is a synchronous step-down DC/DC converter that provides wide 4.5V to 23V input voltage range and 3A continuous load current capability. FR9888 Fault protection includes cycle-by-cycle current limit, input UVLO, output over voltage protection and thermal shutdown. Besides, FR9888 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 FR9888 supply current is about 1uA.
The FR9888 is available in an 8-pin SOIC package, provides a very compact system solution and good thermal conductance.
