shop/ buck & boost converters/ pololu 12v 4.5a step-down voltage regulator

Efficient 12V from 24V, 36V, or 48V systems. The Pololu D36V50F12 is a step-down (buck) regulator rated up to 4.5A continuous, with far less heat than a linear regulator doing the same drop.

The EN pin gives remote shutoff and the PG output reports power-good status - handy for standby modes and reset logic.

Specs

Model Pololu D36V50F12
Type Step-down (buck) regulator
Input voltage 13.3V to 50V (minimum rises with load)
Output voltage 12V fixed (4% accuracy)
Continuous output current Up to 4.5A (thermally dependent)
Protection Reverse-voltage, over-current/short-circuit, thermal shutdown
Extras EN enable pin, PG power-good output, soft-start
Size 1 in × 1 in

Step-down only: input has to stay above the output plus dropout, so a 12V battery won't hold a 12V rail.

FAQ

Will this ship from Manila?

Yes — all stock ships from our Quezon City warehouse. Order before 4 PM weekdays for same-day cutoff via J&T or LBC.

Do you ship nationwide?

Yes. Metro Manila usually arrives next-day; provincial 1–3 working days.

Can I get this on a school PO or class order?

Yes — we accept Purchase Orders from accredited schools and universities. Contact us with your PO details and we'll process it.

Is this compatible with Arduino, ESP32, or Raspberry Pi?

Most parts work with common maker boards — check the description for specific pinout / voltage notes. If you're unsure, send us a message before ordering.

What's your return policy?

7-day inspection window for DOA units. Email proof of issue and we'll ship a replacement or refund. Used / installed parts are not returnable unless faulty.

Do you offer technical support?

Yes — questions land on our forum or via email, weekday or weekend. We've actually wired up most of what we sell.
