Product Summary
The TPS40192DRCR is a cost-optimized synchronous buck controller that operate from 4.5V to 18 V input. The TPS40192DRCR implements a voltage-mode control architecture with the switching frequency fixed at either 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. The applications of the TPS40192DRCR include Cable Modem CPE, Digital Set Top Box, Graphics/Audio Cards, Entry Level and Mid-Range Servers.
