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 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 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 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 ...
