App note: High-side smart-FETs with analog current sense

Smart-FETs application from ON Semiconductors. Link here (PDF) This application note describes the structure and design philosophy of ON Semiconductor High Side Smart−FETs, and serves as a guide to understand the operation of the device in specific applications. The scope of this document is limited to Smart−FETs with analog current sense output.

App note: Selecting a FET for use with the Si875x driver

Another application note from Silicon Labs on determining the proper FET used on their Si875x driver based on its application. Link here (PDF) The Si875x enables creating custom solid state relay (SSR) configurations. Supporting customer-selected external FETs, the Si875x combines robust isolation technology with a FET driver to form a complete, isolated, switch. Versatile inputs […]

Open Inverter, an open source micro-solar inverter

Ken Boak has been working on an open source micro-solar inverter project: We wanted to make a design that uses readily obtainable N-type FETS and an Arduino (more strictly a ATmega328P-PU on a breadboard) to generate the PWM signals and provide simple circuit protection, and load sensing. With the PWM signals generated in firmware it can easily […]

25A 14V step-down regulator with integrated FETs

McZ writes in with an impressive step-down regulator: The TPS56221 is a high-efficiency synchronous switcher with integrated FETs, which achieves a power density of greater than 200W/in3 with greater than 90 percent efficiency at high loads. The easy-to-use SWIFT step-down regulator supports 25-A point-of-load designs for telecommunications, networking and other applications.
