The LT®3791 is a 4-switch synchronous buck-boost DC/DC converter that regulates both constant-current and constant-voltage at up to 98.5% efficiency with a single inductor. It can deliver hundreds of ...

Scarcely a lighting application exists that designers have not considered converting to solid-state lighting, especially as LEDs by leaps and bounds improve both the quantity and the quality of their ...

Allegro MicroSystems' A6211 switching buck regulator LED driver provides constant-current output to drive high-power LEDs. With a wide input supply voltage from 6 V to 48 V, the device integrates a ...

LED output is a function of the current through it. So to drive the device, it would seem simple enough to set the LED current with a series power resistor. But there’s a problem with this idea. First ...

There are many power management methods that can be used for LED lighting. You can drive them via a number of dedicated driver ICs available on the market, or even use microcontroller units (MCUs) for ...
