7.5V To 18V, 1ch Synchronous Buck DC/DC Converter with an r6A Integrated MOSFET - BD95861MUV

BD95861MUV is a 1ch synchronous buck converter that can generate output voltage (0.8V to 5.5V) at the input voltage range (7.5V to 18V). Space-saving and high efficient switching regulator can be achieved due to built-in N-MOSFET power transistors. The IC also incorporates H3Reg™ technology, a ROHM proprietary constant ON TIME control mode which facilitates ultra-high transient response against changes in load without external compensation components. Fixed soft start function, power good function, and short circuit / over voltage protection with timer latch functions are incorporated. The BD95861MUV is designed for power supplies for Digital AV Equipment.
