More Information
The TPS40197 is a synchronous buck controller that operates from 4.5 V to 14 V input supply nominally. The controller implements voltage-mode control architecture with the switching frequency fixed at 520 kHz. The higher switching frequency facilitates the use of smaller inductor and output capacitors, thereby providing a compact power-supply solution. An adaptive anti-cross conduction scheme is used to prevent shoot through current in the power FETs.
