UM5482S8 Datasheet - Union Semiconductor

UM5482S8 2A Synchronous Step Down DC/DC Converter

The UM5482S8 is a synchronous buck regulator. The device integrates two 130mΩ 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 inrus.
