  1. 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. ...
  2. 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 ...
  3. 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 ...
  4. 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 ...
  5. Dave Salerno, Linear Technology The proliferation of wireless sensors supporting the “Internet of Things” has increased the need for small, efficient power converters tailored to untethered low power devices. The new LTC3129 and ...

  6. Kiril Karagiozov EDN One way you can control the temperature of a soldering iron is with a microcontroller, using temperature feedback from the thermistor in the handle near the iron's tip. This Design Idea presents a soldering iron driver that ...
  7. Hua (Walker) Bai, Linear Technology Design Note 508 Introduction The meaning of the term high power LED is rapidly evolving. Although a 350 mA LED could easily earn the stamp of high power a few years ago, it could not hold a candle to the 20 A LED ...

  8. James Wood EDN The Design Idea in Figure 1 indicates a low-battery condition in an audio test instrument that is powered by four AA cells. As the instrument was otherwise an all-discrete design, this same approach seemed more in keeping with the ...
  9. Mike Shriver, Linear Technology Design Note 505 Introduction The LTC®3838 is a dual output, dual phase buck controller that employs a controlled constant on-time, valley current mode architecture to provide fast load step response, high ...
  10. Clive Bolton EDN This Design Idea drives the 20mA current loops that are often used to control two-way proportional pneumatic or hydraulic servo valves in high power robotics applications. Most current drivers are capable of driving unipolar ...
