Smart power stage with 100+A peak current in 4x6mm package

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 Pb-free 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.
