The AN6485 is a synchronous step-down DC/DC converter that provides wide 4.5V to 24V input voltage range and 3A 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 AN6485 is available in an 8-pin SOIC package, provides a very compact system solution and good thermal conductance.
