Driver for CCD Imager and an OLED Display Panel
With Soft Start - The three outputs of the LT3587 can be
configured to provide positive (+15V AT 50mA) and negative (-8V AT 100mA) bias for a CCD imager as well as 16V AT
20mA to bias an OLED display . . . [Linear Technology App Note - , Mar 24, 2010]

thermally compensates LED - 09/02/99 EDN Design Idea
Optical power of popular types of LEDs decreases with temperature. Optical-power measurements into a typical
multimode fiber at 62. 5/125 ?m for a GCA 1A194 LED indicate a temperature coefficient of approximately -0.

circuit alternately flashes a red/green bi-coloured LED. . . [Name of designer is not given]
Driving a Capacitive Load
- You've been warned! Do not attempt to drive large capacitances
with your op Amp, severe overshoot and ringing may occur. But what if you're stuck driving a length of coax cable
that's unterminated? You could end up with over 1000 pF that sends the output ringing. What causes this behavior?

Driving a N Channel FET from TTL
- Meant as a quick n easy example of how to switch high current12V
dc from TTL. . . .
Driving A Relay
- The 555 will activate a relay. When pins 2 and 6 are connected as
an input, the chip requires only about 1uA to activate the output. This is equivalent to a gain of about 200,
000, 000 (200 million) and represents about 4 stages of Amplification via transistors. . . [Name of designer is

Driving a relay with a CPU -
Try using a simple transistor like a 2N4124 just feed the base from the emitter of the opto-isolator. Don't
forget to put a clamping diode across the relay (reverse biased) and maybe a 1uF cap. Drive the photo transistor
with an IR LED and couple it with some heat shrink tubing. . . . [by Kip J. Mussatt]
Driving a WLED does not always require 4 V
- 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,

Driving an LED with or Without
a Resistor - In this post I will try to show, why it's a
good idea to use a current limiting resistor for an LED. And when it's save to drive the LED without any
resistor. If you read about LEDs, you will notice that everyone tells you, that you need a current. . .

Driving Dot LED
- A basic circuit of the 89C2051 shown here can be made easily using
point-to-point soldering with a universal PCB. Use an ordinary 20-pin socket, do not use a circle-pin socket. D1
is a small dot LED. U2 can be either 7805 or 78L05. U3 is optional for correcting any polarity DC adapter.
