## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE07271:1` (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/CE07271:1.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 buck converter (step-down only) has two potentiometers that adjust the output current limitation and regulated voltage provided. Note the specifications for the exact range and maximum power output.

**Note: The adjustment knobs are 30-turn potentiometers that control the voltage and current limits. This means you may have to turn them up to 30 turns to get from the top of the output limit range (36V) to your target voltage.**

**Specifications**

- Model: XL4015
- Input Voltage Range: DC 4-38V
- Output Voltage Range: DC 1.25-36V Adjustable
- Output Current: 0.16-5A 
    - 3V of dropout (headroom above output voltage) is required to limit current reliably
    - 160mA is about the lowest you can go
    - Short circuits will likely cause the unit to go into overcurrent protection
- Output Power: 75W
- Fixing Hole Diameter: 3mm
- Total Size: 62mm x 26mm x 12mm (L\*W\*H)
- Colour: Blue
