Buck/boost/inverting controller delivers up to 20 A

A synchronous PWM controller for negative-to-negative or negative-to-positive DC/DC conversion, the LT8709 from Linear Technology is easily configured for buck, boost, buck-boost, and inverting topologies to accommodate a wide range of power-supply designs. he device’s synchronous operation means that the output diode is replaced with a high-efficiency P-channel MOSFET, increasing efficiency and allowing for higher […]

Reflow Château – Reflow oven controller

Electronics News Updates / Ibrar Ayyub

Introduction When Adafruit announced their capacitive touchscreen shield, I knew I had to do something cool with it. I mocked up a design for the Château using an Atmega32u4, but once I saw this post on Hackaday, I quickly changed to the Teensy 3.1. Being able to update the display at a reasonable rate makes
