# TPS62827 3.3V Buck Converter Breakout - 3.3V Output 2 Amp Max

**Type:** Product page · **SKU:** ADA4920 · **Brand:** [Adafruit](https://core-electronics.com.au/brands/adafruit-australia)
**Page:** https://core-electronics.com.au/tps62827-3-3v-buck-converter-breakout-3-3v-output-2-amp-max.html ([markdown](https://core-electronics.com.au/tps62827-3-3v-buck-converter-breakout-3-3v-output-2-amp-max.html.md))

This little buck converter based on the TPS62827 is super handy, taking up to 5.5V input and providing a 3.3V output with up to 2A current. It's great for supplying power to hungry 3.3V voltage circuits from a range of battery or power options. This chip provides up to 2 Amp load current across the entire input voltage range of 3.4 to 5.5V. It's not a huge range but does cover LiPoly batteries, 3 alkalines, and USB power.

## Pricing

- **Price:** $12.40 (inc GST) — $11.27 AUD, exc GST
- **Quantity discounts:** 10+ $10.94 (exc GST) · 50+ $10.71 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 3 today, and up to 500 more in 8–12 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA4920:1` (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/ADA4920:1.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 little buck converter based on the TPS62827 is super handy, taking up to 5.5V input and providing a 3.3V output with up to 2A current. It's great for supplying power to hungry 3.3V voltage circuits from a range of battery or power options. This chip provides up to 2 Amp load current across the entire input voltage range of 3.4 to 5.5V. It's not a huge range but does cover LiPoly batteries, 3 alkalines, and USB power.

Great for your portable project, Adafruit made this "pin compatible" with the LM1117-3.3V TO-220 chip so you can swap it in for better performance (90-95% efficiency!) There's also an ENable pin, tie it low to shut down the output completely.

The **Adafruit TPS62827 Breakout** runs at 2.2-MHz fixed-frequency. Even though the chip itself supports up to 4A, Adafruit found that 2 Amps or so was a good max to stick to for constant current draw and 3 Amps for temporary peak current draws. Adafruit did use a 2 oz copper double-layer PCB.

If you need a wider input range, [check out the 3.3V output MPM3610 breakout with up to 20V input](https://core-electronics.com.au/mpm3610-3-3v-buck-converter-breakout-21v-in-3-3v-out-at-1-2a.html)!

Comes with a fully assembled and tested breakout board. We also include header to plug it into a breadboard.
