Key Specifications

 

The UM5482S8 is a synchronous buck regulator. The device integrates two 100mΩ MOSFETs, and provides 2A of continuous load current over a wide input voltage of 4.75V to 18V. Current mode control provides fast transient response and cycle-by-cycle current limit.

An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 1μA.

This device, available in an 8-pin SOP package, provides a very compact solution with minimal external components.
