App note: Introduction to schottky rectifiers

Sunday, August 3rd, 2014

App note(PDF) on schottky rectifiers from Microsemi. Schottky rectifiers have been used for over 25 years in the power supply industry. The primary advantages are very low forward voltage drop and switching speed that approach zero time making them ideal for output stages. This latter feature has also stimulated their...

App note: What is a silicon transient voltage suppressor and how does it work

Sunday, August 3rd, 2014

A primer app note(PDF) on silicon transient voltage suppressors by Microsemi. Silicon transient voltage suppressors (TVSs) are clamping devices that limit voltage spikes by low impedance avalanche breakdown of a rugged silicon pn jucntion. They are used to protect sensitive components from electrical overstress such as that caused by induced...

App note: Hiccup-mode current limiting

Sunday, July 20th, 2014

This is fairly old but interesting over current protection using Hiccup-mode from Microsemi. PDF here. Hiccup-mode is a method of operation in a power supply whose purpose is to protect the power supply from being damaged during an over-current fault condition. It also enables the power supply to restart when...

app note: A simple current-sense technique eliminating a sense resistor

Sunday, July 13th, 2014

An old but interesting app note(PDF) from Microsemi on resistorless current-sensing technique. This application note introduces a simple current-sense technique that eliminates that sense resistor, resulting in system-cost reduction, PCB space saving, and power efficiency improvement. Furthermore, the new current sensing mechanism allows higher dynamic tripping current than the static...
