Most LED driver circuits use a series resistor to control the current through the LED. For applications needing a few LEDs, this is optimal. However, for applications needing many LEDs, this becomes ...

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

The HV9803 is a LED driver IC with average-mode constant current control and operates in a constant off-time mode. It can be powered from a 7.0 – 13.2 V supply. The device is equipped with a current ...

The HV9961, an average-mode, constant-control LED driver IC designed to drive LEDs using a buck topology, is well-suited for a variety of solid-state lighting applications. The HV9961 provides current ...
