TPS40197 Datasheet (Texas Instruments)

TPS40197, 6-A Buck Controller

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 capacito
