The HV9967 LED driver is an open loop, average-mode current control device that operates in a constant off-time mode. The IC includes a 60 V, 0.8-Ω MOSFET that can be used as a stand-alone buck ...

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 ...

Light-emitting diodes have become the lighting source of choice for almost all illumination applications. Incandescents, fluorescents, CFLs, and other types are fading away in favor of the almighty ...

The holiday gave me a chance to play with bipolar transistor mosfet drivers again. And things did not go quite as planned. I had been using the circuit on the right quite happily from a signal ...

Dimming LEDs is an important feature in many of today’s solid state lighting applications. While many implementations for dimming LEDs in the market today rely on PWM modulation of the LED driving ...
