Old app note from Fairchild Semiconductors on SO-8 power MOSFETs’ power handling. Link here In applications requiring high current and small footprint electronic switches, a Power MOSFET packaged in an SO-8 is usually the best choice. This is because the combination offers low on-resistance and reasonable power handling. A second benefit is the numerous suppliers […]
App note(PDF) from NXP on DC-DC medium power small-signal MOSFETs. This application note explores different methods of DC-to-DC conversion. It includes some examples of DC-to-DC down-converters using small-signal MOSFETs.
Elmars Ositis has been working on a simple constant current driver: In my previous post, I slapped together a quick LED lighting solution for my workbench… but it is truly a hack. What I really want to do is make a simple constant current driver, so the power LEDs can be used in other projects. One […]
A DIY 60W adjustable electrical load project from Electro-Labs: In this project, we are building a useful board which should take place on your bench. It is an adjustable electrical load which can sink up to 5A @ 60W continuously. This board will come to aid when you need to draw an exact amount of current […]
An app note from International Rectifier on using P-Channel MOSFETs P-Channel HEXFET Power MOSFETs offer the designer a new option that can simplify circuitry while optimizing performance and parts count. In principle, nothing can be done with a P-Channel MOSFET that cannot be done with an N-Channel plus some extra gate drive circuitry. The main […]
App note from International Rectifier on Power MOSFET Basics This application note discusses the breakdown voltage, on-resistance, transconductance, threshold voltage, diode forward voltage, power dissipation, dynamic characteristics, gate charge and dV/dt capability of the power MOSFET.
An application note from Microchip: Avoiding MOSFET driver overstress (PDF!) This application note describes how to avoid MOSFET driver overstress. MOSFET drivers are used in many applications to drive the high input capacitance of a power MOSFET device. MOSFET drivers are very reliable when used within their operating specifications. Care must be taken, however, to […]
An introduction to the MOSFET: If you need to switch high current and or high voltage loads with a micro controller you’ll need to use some type of transistor. I’m going to be covering how to use a MOSFET since it’s a better option for high power loads. This guide will be just a brief […]
