- **Quantity discounts:** 6+ $7.60 (exc GST) · 12+ $7.28 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 86 today, and up to 1900 more in 8–12 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR1015:1` (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/DFR1015:1.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

Multiple-output DC–DC converters are essential in a multitude of applications where different DC output voltages are required.

This DC-DC step-down voltage power module converts 7.5V~30V input to an output of 3.3V/5V/9V/12V (default to 5V), which can be selected by short-circuiting the corresponding pads on the back. It withstands up to 5A load current with suitable heat dissipation and has 70°C over-temperature and overload protections. Besides, there is an onboard LED indicator that shows a solid red light when everything works fine and goes out when the protection mechanism is triggered and the voltage automatically drops to 0.1V.

The multi-voltage buck power module can be used in power control systems for LEDs, robots, drones, servos, low-power motors, and so on.

### Instruction

This module outputs 5V by default and the corresponding 5V solder pad is short-circuited. To output other voltages, for instance, 3.3V, please disconnect the 5V pad and short circuit the 3.3V solder pad.

Note: Since this is a step-down converter, the input voltage should be larger than the output, and it works better with a voltage difference of 2V and above.
