Switching Regulator ICs
with Built-in FET (5V)
BD9634GU
General Description
BD9634GU is a system switching regulator IC for
DSC/DVC applications to generate plural voltage high
efficiently from battery. Component for Power FET and
phase compensation are embedded so it is suitable for
compact type DSC/DVC application.

Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.
