A better approach is to use the LT1618 constant-current, constant-voltage converter, which combines a traditional voltage-feedback loop and a unique current-feedback loop to operate as a ...

Basic LED driving options At a basic level, a single string of LEDs is easy to drive: place a current-limiting resistor between the AC or DC source and the LED; for use from an AC line, LEDs can be ...

Second, the pass transistor’s (VT1’s) load-current capability depends on its base current, which depends on the number of LEDs used in series (that is, on output voltage).

We'll talk about three big ideas: electric potential difference (voltage), electric current, and electric field. Yes, they are all related, and I will show you how with some water and an LED.

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 ...

Migration from incandescent lighting to solid state alternatives is continuing, but if LED adoption is to reach applications such as replacement lamps in the domestic environment or automotive ...

Linear Technology has announced the LT3909, a high efficiency, constant current LED driver that can drive two strings of up to 10 LEDs at 50mA. To ensure constant brightness, each LED string contains ...

Date Announced: 08 Oct 2007 -- The NCP3065 reduces power dissipation in the sense resistor by 80 percent compared to competitive solutions and delivers 2 percent better total system efficiencyPHOENIX, ...

Date Announced: 24 Sep 2012 Plano, Texas – Delivering a constant current of up to 150mA, the AL5812 60V linear LED driver from Diodes Incorporated provides designers of low-current illumination and ...

The new series of constant current regulators is based on patent-pending self-biased transistor technology, and is targeted for a broad range of LED applications with varying input voltage.

Despite how useful multimeters are, there are a lot of limitations you just don’t think about because they’re the way electronic measurement has always been done. Want to measure voltag… ...
