Description

TPS40192 and TPS40193 are cost-optimized synchronous buck controllers that operate from 4.5 V to 18 V input. These controllers implement a voltage-mode control architecture with the switching frequency fixed at either 600 kHz (TPS40192) or 300 kHz (TPS40193). 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.
