In this case, a PIC12F1501. A PIC alone won’t handle a 10 watt LED, so he utilized a CAT4101 constant current LED driver from ON Semi. The PIC performs three tasks in this circuit.

This simple LED driver circuit allows us to drive up to seven LEDs by using a single NiMH (Nickel Metal Hydride) AA cell. The circuit produces voltage pulses at a much higher level than the input ...

Using an IRFZ44N, I made a simple LED driver and used an Arduino Uno directly. Remember the Arduino pins go up to 5V and I used the fade example that generates PWM out of the box.

Power Integrations, a provider of high-voltage integrated circuits for power conversion, announces the latest application of its innovative power conversion technology, unveiling a simple, ultra-low ...

A Simple Over-Voltage Protection Circuit for LED Drivers This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V ...

Most common driver varieties use some of the same topologies as used in these basic regulator dc-dc converter circuits. Figure 2 shows the most common topologies, all of which use MOSFET switches. 2.

Suppose we want to drive an LED string with 400 mA. Drivers U1 and U2 (MAX16803) are good for automotive use because they have a high input-voltage range, excellent thermal qualities, and the ...

We will look at alternatives to implement analog dimming on conventional LED driver circuits, and a complete solution based on a simple, minimal-external-components architecture will be presented ...
