Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

The TPS7510x linear low dropout (LDO) matching LED current source is optimized for low power keypad and navigation pad LED backlighting applications. The device provides a constant current to up to ...

Usually, an MCU is considered a digital device. By default, its output voltage level can be either high or low and nothing in between. With the requirement to create an LED brightness control, the ...

The HV9931 is a fixed-frequency, pulse-width-modulated (PWM), offline LED driver IC with built-in power factor correction (PFC). It is designed to control an LED lamp drive using a proprietary ...

This module introduces Pulse Width Modulation (PWM) techniques for Python on the Raspberry Pi. Subsequently, by using PWM we can modify the brightness of an LED without having to change a resistor.
