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.

This 400-kHz automotive boost LED driver has filters for low EMI and an option for 100%, 10%, or 1% internally generated PWM dimming. EMI tests (see Figure 5) show that this solution passes CISPR ...

The LT3932 synchronous step-down LED driver with integrated 36V, 2A switches features high ratio PWM dimming. The LT3932 houses its high efficiency integrated power switches inside a small 4mm × 5mm ...

Linear Technology’s LT3932 step-down DC/DC converter offers fixed-frequency, peak current control and PWM dimming for a string of LEDs. The device accurately regulates LED current to within ±1.5%, ...

Fast 33MHz Serial Bus with Cascade Operation for mini-LED backlights and Large Displays 48-Channel LED Driver IC with 16-bit PWM and Programmable Current Adjustments A high-speed serial bus for ...

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.

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 ...

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 ...

Macroblock has launched a new 16-bit PWM LED driver, MBI5040, with 8-bit digital dot correction. The new digital dot correction designed in MBI5040 not only unifies the LED brightness and avoids ...

A widely used driver is the dc-dc converter with PWM. The PWM approach varies the duty cycle of applied pulses to control the average LED current and the brightness.

Drivers with dimming capability can dim the LED light output over the full range from 100% to 0%. They do so by reducing the forward current or by using pulse width modulation (PWM) via digital ...
