3 Description
The CSDM65695x family of devices are 4-phase
smart power stage modules with high peak
current capability. The device family is highly
optimized design for use in high-power, high-density
synchronous buck converter applications. This
product family integrates the driver IC and power
MOSFETs into one Pb-free monolithic design to
complete the power stage switching function. There
are VIN and VCC bypass capacitors integrated
into the package for minimum loop inductance and
improved ringing.
This combination produces high-current, highefficiency,
and high-speed switching capability in a
small industry standard 9 mm x 10 mm x 5mm
footprint.
CSDM65695x integrates accurate current sensing
and temperature sensing functionality to simplify
system design and improve accuracy. This power
stage module also includes cycle-by-cycle current
limiting, over temperature and short circuit protection,
and is designed to be compatible with TPS537xx
series controllers.
