Product details

The TPS54302DDCR: The adjustable output down to 0.596 V makes it a fit for powering 3.3 V, 5 V, or 1.8 V logic rails from a 12 V or 24 V industrial bus.

Switching frequency and synchronous rectification

The fixed 400 kHz switching frequency allows a compact inductor and output capacitor while keeping switching losses moderate.

The SOT-23-6 Thin package occupies minimal board area and supports automated assembly.

Frequently asked questions

Can TPS54302DDCR be used for 12 V input?

Yes. The 3 A output is available across the full input range, subject to thermal derating.
