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.
The TPS40197 integrates the PWM control and 4-bit VID interface in a single chip to allow seamless on-the-fly VID changes with programmable transition rate. It provides a simple power solution for Smart-Reflex™ DSP cores.
Short circuit detection is done by sensing the voltage drop across the low-side FET when it is on and comparing it with a user selected threshold of 100 mV, 200 mV or 280 mV.
