TPS40192 and TPS40193 are cost-optimizedsynchronous buck controllers that operate from 4.5 Vto 18 V input. These controllers implement avoltage-mode control architecture with the switchingfrequency fixed at either 600 kHz (TPS40192) or 300kHz (TPS40193). The higher switching frequencyfacilitates the use of smaller inductor and outputcapacitors, thereby providing a compactpower-supply solution. An adaptive anti-crossconduction scheme is used to prevent shoot throughcurrent in the power FETs.
