## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR1202:1` (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/DFR1202:1.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 provide reliable power conversion with high efficiency. It accepts a wide **input voltage range from 6V to 24V and provides a stable 5V output**, supporting **up to 16A of current**. The module is equipped with key features such as over-temperature protection (up to 125°C), output short circuit protection, and an output ripple noise of less than 20mV. Achieving conversion efficiency greater than 90% under typical conditions (12V input with 1-16A load), this module is ideal for applications that require a stable and efficient power supply, such as driving multiple motors or servos in robotics, high-power LED lighting systems, automotive electronics and DC-powered devices, smart robots, drones.

**High Efficiency and Low Ripple**

The module achieves a conversion efficiency of over 90% with a 12V input and 1-16A load, ensuring minimal energy loss. Its output ripple noise is maintained below 20mV, making it suitable for sensitive electronic devices and precision applications.

**Robust Protection Mechanisms**

Equipped with 125? over-temperature protection and output short-circuit protection, the module ensures reliable operation even under harsh conditions. These features safeguard both the module and connected devices from potential damage.

**Enhanced Heat Dissipation**

A thermal pad on the back of the module allows for soldering to a large copper area, significantly improving heat dissipation capabilities. This design ensures stable performance even during prolonged high-current operation.

The module features three control pins:

11. EN: Enables or disables the output when connected to a microcontroller's IO pin (with a 1K resistor in series).
12. AGND: Provides a single ground point for microcontroller control.
13. PGOOD: Outputs a high level (5V) when the output voltage is normal and a low level (0V) during abnormal conditions or short circuits.
