This power module contains the function of automatic buck-boost and integrates with the related circuit of buck-boost converter. Its mini body is very easy for embedding...

## Pricing

- **Price:** $5.95 (inc GST) — $5.41 AUD, exc GST
- **Quantity discounts:** 6+ $5.14 (exc GST) · 12+ $4.92 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 8 today, and up to 160 more in 8–12 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0568:1` (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/DFR0568:1.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 contains the function of automatic buck-boost and integrates with the related circuit of buck-boost converter. Its mini body is very easy for embedding.
Input voltage range 2.5-15V, fixed output voltage 3.3V, the maximum load current is 0.6A and its quiescent current is as low as 200uA. In theory, the work frequency of the module can reach to 1.2MHz. Besides, it has steady output voltage, which can work long time without voltage shift and is suitable for the occasions with high requirements. You can use this power module to DIY mobile power bank and provide constant power for your project.

### Features

- Small size
- Stable performance
- Wide voltage range for a variety of DIY applications

### Applications

Power supply for controller main-board, DIY current source, floodlight, DIY toy car, communication device, digital radio.

| Serial number | Name | Direction | Application |
|---|---|---|---|
| 1 | Vo+ | output | Output positive current source |
| 2 | Vo- | output | Ground wire, output port current source reference |
| 3 | Vi- | input | Ground wire, link to current source reference |
| 4 | Vi+ | input | Power supply input:2.5-15Vdc |

**NOTE**

1. The input voltage must within 15V.
2. Load current should not be in 600mA or above for a long time, otherwise, it will affect the service life of the module and even burn out.
3. If the load current is relatively high, you should increase the minimum input voltage to ensure normal operation.
