TPS40197 Overview
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 pact power-supply solution.
