TPS40193 - Synchronous Buck Controller

Download the TPS40193 datasheet PDF. This datasheet also covers the TPS40192 variant, as both devices belong to the same synchronous buck controller family and are provided as variant models within a single manufacturer datasheet.

General Description

TPS40192 and TPS40193 are cost-optimized synchronous buck controllers that operate from 4.5 V to 18 V input.

These controllers implement a voltagemode control architecture with the switching frequency fixed at either 600 kHz (TPS40192) or 300 kHz (TPS40193).
