Temperature Controller Drives Peltier Cooler
- 06/08/95 EDN Design Idea The circuit in "Peltier element controls itself,"
by Dmitrii Loukianov ( EDN, October 27, 1994, pg 86) is elegant, but it suffers from two potential problems that
could arise in some applications. The first is possible switching-noise injection from. . . [by Dr Trevor

Ten-LED Sequential Flasher using Low Powr
- A while back I posted a flasher circuit which flashed 10 LEDs sequentially.
That circuit was powered by four AA alkaline cells. The circuit below operates much the same way but has been
modified to run from a single 3v CR2032 lithium coin cell . . . [Circuit by Dave Johnson P.E., 04/17/11]

VCOM Drivers - 11-Nov-04 EDN Design Idea Flat-panel LCD
monitors offer excellent image quality and compact form factor than CRTs—hence, their steadily increasing
popularity. Unfortunately, the complexity of their manufacturing process makes LCD monitors considerably
expensive. . . [by Soufiane Bendaoud, Analog Devices, San Jose, CA]
Tester for Pulsed
LEDs - This circuit is designed to test visible and
infrared LEDs in pulsed mode operations. It can drive the LED with peak currents in excess of 10 Amps. A light
detector nearby can monitor the response time and intensity of the LED under test . . . [Hobby Circuit designed

The Audio/ Video Distribution
Amplifier - With the amount of equipment in home
entertainment centers today the need to be able to vary the gain of the audio or video signal is needed. I found
this particular circuit helpful when used in conjunction with the Universal Descrambler and a Stabilizer circuit
I built for making copies of video tapes. . . [Randy Linscott's site]
The LM3410 LED Driver - The
LM3410 IC is a constant current LED driver useful in either boost converter or SEPIC design applications. A SEPIC
(Single Ended Primary Inductance Converter) design allows the power supply’s output voltage to be set above,
below or equal to its input voltage. must register on this site. . . [Published in Elecktor July/Augu, 2010]

96.12Msps with a 70MHz, 4-Channel WCDMA Signal - 70MHz IF
signal driver into ADC. Four to one transformer on input with capacitive coupling into input of LT1993-2, LC
filter on output provides Out of Band Filtering. . . . [ Linear Technology App Note - , Jul 2, 2012]
The Use of Zetex E-Line Transistors in
Motor & Solenoid Driver Functions Within Printers: Effective Logic to High Current Load Interfacing
- Zetex Semiconductors Applications Notes A brief discussion of the
drive requirements of relatively high current inductive loads within computer peripheral equipment, with respect
to the benefits possible with optimised small packaged components. . .
Thermal Performance of the LM3404/04HV in SO-8 and PSOP-8 Packages (Rev. A)
- LED lighting designers are challenged with meeting their efficiency and
reliability goals faster in advanced LED lighting designs. LED lighting customers seeking the latest in
innovative and affordable LED lighting solutions can benefit from TI's broad product portfolio of LED drivers,
AC/DC, DC/DC, power management devices, wireless and wired interface control and embedded processors. LED
designers have the option of not only controlling the power stage, but regulating LED currents as well,
eliminating the need for multiple components and reducing system cost. . . . [Texas Instruments App Notes,
