Class I or II LED driver What's Class I? What's Class II? IP rating of LED driver Input voltage and wattage Output Power of LED driver Output voltage and output current Determine the number of LEDs. What do we
Determine the LED forward diode voltage. Look on the LED data specification sheet from the manufacturer. For this example, you might find "2.0 volts" listed on the data spec sheet. Determine the voltage setting of the power supply. Multiply the number of LEDs by the diode forward voltage. F...
Samsung washing machine dryers should be properly sealed to maximize energy efficiency, with a thin felt seal on the front of the drum and a thicker fabric seal around the back. When these two seals are in good condition and properly positioned, they keep heat inside the drum, allowing the ...
Confused about how to connect an LED strip to a DC power supply? We've created a step-by-step guide that doesn't require soldering!
Perform initial evaluation of the part by determining the number of digital interfaces it has and what type it is (for example, input, open-drain, 3-state, etc.).From the device data sheet, determine the operating supply voltage, operating temperature, integrated circuit...
Last year 3.15 evening scene test link, the moderator for consumers introduced a verification of the quality of LED light simple way: with mobile phone camera to the light bulb, if the viewfinder appe
are not I/O pins but are needed the operation of the module. This leaves GPIO0, GPIO2, TX and RX available as possible I/O pins, but even these have pre-assigned functions. The GPIO0 and GPIO2 determine what mode the module starts up in and the TX/RX pins are used to program th...
There are a few methods to determine how much RAM your motherboard can support. You can check the motherboard documentation and find the specifications section. Once you've located the specifications section, you should be able to see the maximum amount of system memory that can be installed ...
TheMAX20446is a peak current-mode-controlled LED driver, capable of driving up to six LED strings in several different configurations: boost, buck-boost, SEPIC, and flyback topologies. This application note focuses on the boost topology in which the LED string forward voltage is alw...
Here’s everything You Need to Know About Schottky Diodes. Learn how Schottky diodes work in RF circuits, generators, and motor drivers with their low forward voltage drops and fast switching speeds. Like other diodes, the Schottky diode controls the direction of current flow in a circuit. ...
