LED driver using UC3842
So this simple circuit is driving the LEDs at 500mA, suitable for high-powered LEDs. The next step is to calculate the power dissipation: P=I^2 * R = 0.5^2 * 4 = P = 1W. Dissipating 1W is a lot for a single resistor, and requires a 2512 sized or larger surface mount resistor.

International prices may vary due to local duties, taxes, fees and exchange rates. The MAX16834 is a current-mode high-brightness LED (HB LED) driver for boost, boost-buck, SEPIC, and high-side buck topologies. In addition to driving an n-channel power MOSFET switch controlled by the switching controller, it also drives an n-channel.
High Power LED Driver Circuit YouTube
We are almost always surrounded by light from LEDs in organic LED (OLED) TV screens and active-matrix OLED displays in mobile phone screens. LEDs are everywhere, in workplaces, headlamps, and stadium lights. They have gained immense popularity as power-saving, compact, durable, and sustainable alternatives to conventional incandescent and fluorescent lighting systems. But there is a catch.

1 Actually, it will recharge much more than that. The pulse duty cycle is only 0.1%, so a nominal 20A pulse current will only require 20 mA average, and a 0.2 volt drop across the 10 ohms, which is also supported by i/c = dv/dt, So the caps will remain charged to within better than 0.5 volts of the supply voltage. - WhatRoughBeast
High Power pulsed LED driving circuit Electrical Engineering Stack Exchange
Step 1: Overview / Parts There are several common methods out there for powering LED's. Why all the fuss? It boils down to this: 1) LED's are very sensitive to the voltage used to power them (ie, the current changes a lot with a small change in voltage)
1W LED Driver Xtreme Circuits
The basic principle behind the 230V LED Driver circuit is transformer less power supply. The main component is the X-rated AC capacitor, which can reduce the supply current to a suitable amount. These capacitors are connected line to line and are designed for high voltage AC circuits.

The circuit of Figure 1a is very popular for LED drivers from DC voltage sources (usually batteries). The following schematic shows the typical Buck LED driver circuit from a DC source: Figure 2. DC-BUCK LED driver. The driver is powered from the input voltage and drives a PMOS. A sense resistor in series with the LED load generates a voltage.

Electronics & Electrical Alok Jha Simple 1watt to 12watt SMPS LED driver circuit
Power LED Driver Circuit Here's a really simple and inexpensive Power LED driver circuit. The circuit is a "constant current source", which means that it keeps the LED brightness constant no matter what power supply you use or surrounding environmental conditions you subject the LED's to.
1W LED Driver Circuit Basic Electronics
An LED driver is an electronic circuit specially designed to drive or illuminate a set of LEDs safely through controlled current and voltage output, as per the specifications of the LEDs. Since LEDs are vulnerable semiconductors devices, they must be driven using a regulated current and voltage power supply.
12v led driver circuit diagram
By contrast, constant Voltage LED driver circuits are designed for LEDs that need steady Voltage - typically 10V, 12V or 24V DC. This makes them best suited to LEDs arranged in a line or string - e.g. lighting strips or similar configurations parallel to the driver.. High Power LED Drivers. The power of LEDs is growing steadily - some.
3 Watt, 5 Watt LED DC to DC Constant Current Driver Circuit Circuit Diagram Centre
In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.
MP3302 LED driver circuit diagram Feedback, Suggestions, and Questions General Topics
An LED is a P-type N-type (PN) junction diode that allows current flow in only one direction. Current starts to flow once the forward voltage (V F) of an LED is reached. LED brightness is driven by the forward current (I F); how much current an LED draws depends on the applied voltage. While I has

The circuit is a "constant current source", which means that it keeps the LED brightness constant no matter what power supply you use or surrounding environmental conditions you subject the LED's to. Or to put in another way: "this is better than using a resistor". It's more consistent, more efficient, and more flexible.
