# DC-DC Power Module 25W

**Type:** Product page · **SKU:** DFR0205 · **Brand:** [DFRobot](https://core-electronics.com.au/brands/dfrobot-australia)
**Page:** https://core-electronics.com.au/dc-dc-power-module-25w.html ([markdown](https://core-electronics.com.au/dc-dc-power-module-25w.html.md))

This Power Module is a small size 5A 350KHz 25V Buck DC to DC Converter.It can convert any DC voltage between 3.6V-25V to a selectable voltage from 3.3V to 25V. You can choose 5V direct output voltage with the switch or adjust the output voltage by the blue&white resistor.

## Pricing

- **Price:** $14.40 (inc GST) — $13.09 AUD, exc GST
- **Quantity discounts:** 6+ $12.44 (exc GST) · 12+ $11.91 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 8 today, and up to 900 more in 8–12 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0205:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/DFR0205:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

This Power Module is a small size 5A 350KHz 25V Buck DC to DC Converter.It can convert any DC voltage between 3.6V-25V to a selectable voltage from 3.3V to 25V.

You can choose 5V direct output voltage with the switch or adjust the output voltage by the blue&white resistor.It is onvenient for you to choose three different interfaces of output.The Ovout interface can output the original voltage of input.so that can be used as the power of other module.

The ON/OFF button on the board can be pulled high to turn the converter module on and low to turn it off.

Cautions: The input voltage must be higher than output voltage.
