3 Description

The CSD965200 power stage is a highly optimized

design for use in a high-power, high-density

synchronous buck converter. This product integrates

the driver IC and power MOSFETs into one Pbfree

monolithic design to complete the power stage

switching function. There are VIN 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 4mm

x 6mm footprint.

Furthermore, CSD965200 is built with a Thermally

Enhanced Package (TEP) using additional top side

cooling for improved heat dissipation. TEP yields

performance benefit, especially at high load currents.

CSD965200 integrates accurate current sensing and

temperature sensing functionality to simplify system

design and improve accuracy. This power stage

also includes cycle-by-cycle current limiting and

protection based on HS FET current sense, HS FET

short and over temperature detection and protection,

negative over current detection, open pin detection,

handshaking and system diagnosis when paired with

the TPS536xx and TPS537xx series controllers.
