Product details

What the TPS40193DRCR is and where it fits

Switching frequency is fixed at 300 kHz, which balances inductor size against switching losses. The 85% maximum duty cycle supports moderate step-down ratios without pulse-skipping. Control features include an enable pin for sequencing and a power-good output for rail monitoring. The part is rated for the industrial temperature range of -40°C to 85°C, covering most factory-floor and outdoor telecom enclosures.

Package and PCB considerations

Mounting is surface-mount only. The shipping options include Tape & Reel (TR) for automated pick-and-place and Cut Tape (CT) for prototype or low-volume builds.

Sourcing and lifecycle

The TPS40193DRCR is listed as Active in production with ROHS3 compliance.

Frequently asked questions

What is the switching frequency of TPS40193DRCR?

The switching frequency is fixed at 300 kHz. There is no clock synchronization input, so the frequency is not adjustable or synchronizable to an external clock.
