TPS40193 Datasheet Synchronous Buck Controller

Manufacturer: Texas Instruments

Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community Reference Design TPS40192, TPS40193 SLUS719H – MARCH 2007 – REVISED MAY 2019 TPS4019x 4.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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).

The higher switching frequency facilitates the use of smaller inductor and output capacitors, thereby providing a compact powersupply solution.
