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 H3RegTM
technology, a Rohm proprietary
constant ON TIME contro
l 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.
