LEDs for lighting are found anywhere from DIY IoT modules to commercial lighting applications and the cabins of airplanes. To run properly, these critical lighting devices require a precise balance of ...

The LED driver automatically adjusts the output voltage to keep the output current constant and therefore the light output constant. This works with a single LED or with a chain of string of LEDs ...

The heart of the device that [Kerry] designed is based on 6 power MOSFETs, a few operational amplifiers and an Arduino compatible ATmega328p microcontroller. Sense resistors are used to measure how ...

The LT3954, a DC/DC converter designed to operate as a constant-current source and constant-voltage regulator with an internal 5A switch, is now available from Linear Technology. The device’s internal ...

The LT3796 series of 100V, high-side current sense DC/DC controllers from Linear Technology are designed to regulate a constant current or voltage. Used for driving high brightness LEDs, the devices’ ...

Current limiting diodes (CLD) regulate current over a wide voltage range. CLDs are used in many applications. Some examples include waveform generators, battery chargers, and timing circuits. CLDs are ...

RS26P and GP-RS35P LED Drivers for indoor lighting solutions 7 November, 2013, New Delhi, India – GlacialPower, a division of ...

Constant voltage transformers (CVTs), or ferroresonant transformers, produce a constant secondary (output) voltage for varying primary (input) voltages within a certain range. With CVTs, the ...

A well-known solution for electrical noise in industrial plants is the constant-voltage transformer, or CVT. These devices can filter distortion and notches from input voltages (see Fig. 1). CVTs have ...

At first glance, [RobBest]’s constant current source looks old school. The box is somewhat old-fashioned, featuring switches and binding posts. Most importantly, there’s a large analog meter ...
