Deivaraja Ramasamy EDN This Design Idea is able to turn off inductive loads at a very fast rate. When connected to a load (here 15 mH + 10 Ω), the modified freewheeling path in the clamping circuit based around M2 reduces the turn off time to ...

Charlie Zhao, Linear Technology Design Note 512 Introduction The trend in automobiles and industrial systems is to replace mechanical functions with electronics, thus multiplying the number of microcontrollers, signal processors, sensors, and other ...

Yi Sun, Linear Technology Design Note 517 Introduction The LTC3883 is a single phase synchronous step-down DC/DC controller featuring a PMBus interface for digital control and monitoring of key regulator parameters. It has integrated MOSFET gate ...

Wei Gu LT Journal In a flyback converter, current levels in high current applications are constrained by heat produced in the output rectifier diode. The clear way to lift this restriction is to replace the diode with a much lower voltage drop ...

Larry Beaty, Beatys Mills EDN This Design Idea came about as a result of my not having access to those wonderful new ICs that sense current. I needed a discrete circuit that I could build easily but that would still be as accurate as the new ICs. ...

By Shawn Rhen Digi-Key The advancements in high powered LEDs have brought them to the attention of the lighting industry, positioning them as replacements for the current incandescent and fluorescent technologies. Although widespread adoption has ...

Yan-Niu Ren, Southwest Petroleum University, Chengdu, China EDN A constant current is better than a constant voltage for driving LEDs. In this proposed circuit, a common constant-voltage regulator is changed into a constant-current source for LEDs. ...

Zhongming Ye, Linear Technology Design Note 509 Introduction Flyback converters are widely used in isolated DC/DC applications because of their relative simplicity and low cost compared to alternative isolated topologies. Even so, designing a ...

George H. Barbehenn, Linear Technology LT Journal of Analog Innovation The LTC3245 is a buck-boost regulator that dispenses with the traditional inductor, and instead uses a capacitor charge pump. The LTC3245’s input voltage range is 2.7 V to ...

Alan Stummer Electronic Design Use a basic op amp and discrete components to drive a piezoelectric motor and provide circuit protection. A piezoelectric motor is a linear motor with bidirectional motion. It uses friction to grip the armature while ...
