LED backlight drivers in the A8060x family from Allegro employ pre-emptive boost control, which reduces output voltage ripple and eliminates audible noise from ceramic output capacitors during PWM ...

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 ...

This is a design example report of a 14 W PWM-analog dimmable LED driver employing LinkSwitch™-PH LNK406EG. This design features high efficiency, power factor correction, low component count, and ...

Automotive LED drivers should be compact, efficient and support flicker-free PWM dimming. They should not produce significant conducted EMI at and around the AM radio band. Unfortunately, low EMI is ...

This library is to control the I2C PCA9634 PWM extender. The 8 channels are independently configurable in steps of 1/256. This allows for better than 1% fine tuning of the duty-cycle of the PWM signal ...

TDK-Lambda announces the new LEDC10 series of dc-dc, LED Drivers that are designed for LED lighting applications with output ratings up to 10 watts. The LEDC10-12-R48 is a non-isolated, ...

Abstract: Light-emitting diode (LED) drivers for automotive lighting applications adopt pulsewidth modulation (PWM) vis-à-vis pulse frequency modulation because its ensuing electromagnetic ...

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 PWM channel is defined in the device tree overlay file, but the GPIO that is mapped to this channel is defined in Kconfig. The current implementation is swapping the configured PWM channel with ...
