This is a story about a successful system that nevertheless failed to make the cut. An experimental LED brightness adjustment is something [Mitxela] explored in a project for a high-precision clock; ...

Maxim Integrated Products introduces the MAX16831 high-voltage, high-power, constant-current LED driver with analog and PWM dimming. This LED driver integrates a floating LED current-sense amplifier ...

The LM3630A is a current mode boost converter which supplies the power and controls the current in up to two strings of 10 LEDs per string. Programming is done over an I2C-compatible interface. The ...

Pulse-width modulation (PWM) is used in applications ranging from controlling valves or pumps to adjusting the brightness of LEDs. In this proposed design, a PWM waveform is the basis for an analog-to ...
