Its 137kHz PWM frequency (in 8-bit mode ... such as high-end appliance control panels and gaming machines. "Our new IS31FL3758 matrix LED driver represents a significant leap forward in LED display ...

Put together on a piece of perfboard, the handwired circuit also includes an Adafruit PowerBoost 500 Charger, a 3.7 V 2500 mAh LiPo battery, a IS31FL3731 Charlieplexed PWM LED driver, and a piezo ...

Using an IRFZ44N, I made a simple LED driver and used an Arduino Uno directly. Remember the Arduino pins go up to 5V and I used the fade example that generates PWM out of the box. The frequency of ...

making it more precise than similar LED drivers available. Alternatively, PWM dimming (0.1 to 1kHz) achieves a 100:1 dynamic range. A soft-start function gradually increases the inductor and ...
