Here is an Arduino based circuit with three independent pulse width modulated (PWM) channels to fulfil your requirements! Just follow the schematic diagram to complete the ... current loads -the ...

As well as thermal de-rating to increase reliability, protections include LED open detection, output short circuit protection, SET pin short circuit protection (see diagram), over-voltage ... and ...

Competition between display manufacturers is driving designers towards high-end LED drivers with integrated PWM functionality capable of delivering thousands of brightness levels. These brightness ...

The LED color is controlled using PWM, as you would expect. What you might not expect however, is the lengths [Simon] would travel to ensure nearly perfect color and brightness matching across the ...

Applying PWM switching to the LED outputs can be particularly troublesome with regards to EMI. To optimize EMI performance, the IS31FL3248 includes a programmable spread spectrum function to lower ...

The LT3952 has a gate driver for a PMOS LED disconnect switch, delivering dimming ratios of up to 4,000:1 using an external PWM signal. For less demanding dimming requirements, the CTRL pin can be ...

Freescale Semiconductor has introduced the MC34845 LED driver with high-speed pulse width modulation (PWM) capability. This six-channel device is designed to allow LED backlights to operate at ...
