High PWM dimming ratio With the LT3932 operating at a dimming frequency of 100Hz and a switching frequency of 2MHz, a high current LED design can achieve 5000:1 PWM dimming with well regulated LED ...

As LED applications continue to diversify, LED drivers must become more versatile. A synchronous LED driver that can be easily used in boost, buck, and boost-buck topologies addresses ...

He built an RGB LED circuit controlled by a PIC12F683 microcontroller, which shines into a hand-etched plexi-glass panel. The LED color is controlled using PWM, as you would expect.

Pulse-width modulation (PWM) Pulse width modulation (PWM) is a powerful technique for controlling analog circuits with a microprocessor’s digital outputs. Pulse-width modulation,as it applies to LED ...

Today we have with us a nice selection of fans from BitFenix. We have the 120mm and 140mm variants of the BitFenix Spectre Pro PWM series. In addition to that we also have the 120mm and 140mm ...

Along the way, you will find detailed notes on the LED’s, PWM Driver, Heat sinking, and capacitive Touch dimmer using Atmel’s AT42QT2160 Qslide – Matrix Sensor IC.

Sunpower’s DAP-04 DALI to PWM converter is designed to provide DALI control in LED lighting applications. The DAP-04 has a DALI input that can accept data from a remote IEC62386-101, 102 or 207 ...

The rear light is of utmost importance for road safety. However, since the space required on the electrical module is limited, several functions must be implemented using just one circuit, for example ...

Rohm has introduced a linear LED driver for automotive use, following close on the heels of its LED driver for motorcycles. BD18336NUF-M is a 3 x 3 x 1mm constant current driver IC that can deliver ...

Google Pixel phones have long had the slowest PWM rate in the industry, but the Pixel 10 Pro family's display aims to fix ...
