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,

high-

efficiency, 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.
