Product details

What this buck controller is and where it fits

The TPS40345DRCT is a synchronous step-down (buck) PWM controller from Texas Instruments, switching at 600 kHz. It takes a 3 V to 20 V input rail and drives a single positive output with up to 90% duty cycle. The controller integrates an enable pin, power-good indicator, and soft-start — the three control signals you actually wire up on a board. The synchronous rectifier means you skip the external Schottky catch diode, saving a component and a bit of board space.

Lifecycle and sourcing

No end-of-life notice, no last-time-buy window to chase. For the BOM line, that means no forced redesign for obsolescence in the foreseeable future.

Frequently asked questions

Does TPS40345DRCT have an enable pin?

Yes. The control features include Enable, Power Good, and Soft Start — the three signals you typically need to sequence and monitor the rail.
