## Pricing

- **Price:** $26.40 (inc GST) — $24.00 AUD, exc GST

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 2 today, and up to 26 more in 8–12 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR1208:1` (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/DFR1208:1.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 DC-DC step-down converter module is designed to efficiently reduce a **high input voltage (15-24V) to a stable 12V output, supporting up to 12A of current**. The module offers high conversion efficiency (over 95%), with minimal ripple noise (under 50mV), making it suitable for power-sensitive applications. It also includes built-in protection features such as over-temperature protection (up to 125°C) and short circuit protection, ensuring the safe operation of both the module and connected devices.

**High Conversion Efficiency**

Achieves greater than 95% efficiency with 24V input and 1-12A load, minimizing energy loss and ensuring reliable power conversion for demanding applications.

**Over-Temperature and Short Circuit Protection**

Features over-temperature protection up to 125°C and output short circuit protection, safeguarding the module and connected devices from damage.

**Thermal Management for High-Current Loads**

A built-in thermal pad allows for enhanced heat dissipation when soldered to a larger copper area, providing improved performance under heavy load conditions.

The module features three control pins:

11. EN: Floating (open) to enable the output, connected to ground to disable the output. It can be controlled by a microcontroller's IO pin with a 1K resistor in series.
12. AGND: When control is needed from a microcontroller, connect a single ground point to this pad.
13. PGOOD: Outputs a high level (5V) when the output voltage is normal. Outputs a low level (0V) when there is an abnormal output voltage or a short circuit.
**Conversion Efficiency**
