Beschreibung
BD95821MUV is a 1ch synchronous buck converter that can generate output voltage (0.8 V to 5.5V) at the input voltage range (7.5V to 15V). Space-saving and high efficient switching regulator can be achieved due to built-in N-MOSFET power transistors. The IC also incorporates H 3 Reg TM 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 BD95821MUV is designed for power supplies for Digital AV Equipment.
