This code supports Application Note AN1138: A Digital Constant Current Power LED Driver, using the PIC12HV615? an 8-pin, PIC microcontroller (MCU) with A Digital Constant Current Power LED Driver The ...

Performing PWM control on the outputs controls the LED luminance. The luminance data of the PWM signal for each LED is stored in three 10-bit registers. Each LED can be dot-corrected by a 7-bit scalar ...

The LED current is adjustable via a high ohmic resistor on a dedicated pin with an IC supply voltage ranging between 6 V and 42 V. For safe and reliable operation and to extend the overall LED ...

Practical LED driver circuit. With the feasibility demonstrated, I designed the previous voltage multiplier LED driver. The output current may be scaled simply via adjusting the capacitor values. All ...

Your 10W LED will need about 10.5V and your constant current circuit will have to drop the difference from the supply voltage. If you feed 14V into the circuit then the 3.5V difference will become ...

LED applications are booming: backlighting for LCD TVs, projectors, and computer displays, camera flashes, and vehicle brake lights and taillights are just a few. All require constant-current LED ...

Phihong USA has developed a new constant-current external LED driver for high power applications, including street and parking area lighting. Resources Directory ...

LEDs are driven with a constant current, with the forward voltage varying from less than 2V to 4.5V, depending on the colour and current. Older designs relied on simple resistors to limit LED drive ...

Fast 33MHz Serial Bus with Cascade Operation for mini-LED backlights and Large Displays 48-Channel LED Driver IC with 16-bit PWM and Programmable Current Adjustments A high-speed serial bus for ...

A circuit like hat is even more useful as a over current limiter – I use a 3.3V regulator and a 100 ohm resistor as a limiter in a power supply that tests 4-20mA current loop devices, so that ...
