NEW PRODUCTS! – Mini DC/DC Step-Down (Buck) Converter – 3.3V @ 1A output – TSR12433 & Mini DC/DC Step-Down (Buck) Converter – 5V @ 1A output – TSR12450. Your power supply problems just got SOLVED! These DC/DC converter step-down switching regulators are drop-in replacements for inefficient 78xx linear regulators. The little module may look tiny but inside is a high efficiency converter (up to 91%) which can output 1 Amp at 3.3V with up to +60°C ambient temperature without the need of any heat-sink or forced cooling (for the 5V version … up to 94% – which can output 1 Amp at 5V with up to +60°C ambient temperature without the need of any heat-sink or forced cooling).
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
This looks like the Cadillac of voltage regulators. My next project may well include some of these — the $15 price isn’t so high when set against the labor cost of me assembling my own on a protoboard. It’s also a lot smaller than anything I’d build. Thank you, Adafruit, for bringing this tech to my attention!
Very very cool. I had been shopping around for a Buck converter to run a Raspberry Pi board from a cordless drill battery, and the 5-volt guy looks better than anything I saw at Digikey. Thank you.
