Product Summary

The TPS40193DRCR is a cost-optimized synchronous buck controller that operates from 4.5 V to 18 V input. These controllers implement a voltage-mode control architecture with the switching frequency fixed at 300 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. Applications include Cable Modem CPE, Digital Set Top Box, Graphics/Audio Cards and Entry Level and Mid-Range Servers.
