About

Advantages of PWM dimming

PWM dimming allows high dimming accuracy converting a 0-10 V analog signal into a PWM dimming signal. Infineon’s dimmable LED interface IC can be used to transmit analog voltage-based signals from a 0-10 V dimmer or potentiometer to the dimming circuit. The PWM input of a lighting controller IC in the form of a current-based PWM signal can also be used to drive an external optocoupler. No additional components are necessary, allowing for a very small design footprint.

Suitable for a full range of applications

A supply voltage of 6 V to 25 V ensures compatibility with all common LED lighting applications including luminaires, troffers, downlights, sconces, office lighting, and signage. LED dimming ICs can also be used for isolated signal transfer in industrial applications.

Better than analog dimming

There are different ways to dim LED lights – analog and PWM dimming. Analog dimming sends DC voltages to the dimmable LED driver IC which then dims the light in response to the voltage received. This method of dimming does not always provide the most accurate dimming. PWM dimming, on the other hand, offers much better dimming accuracy – in this case, an interface can convert an analog 0-10 V dimming signal into a PWM dimming signal. Infineon’s LED interface ICs can be used to transmit analog voltage-based signals from a 0-10 V dimmer or potentiometer to the dimming circuit. This also includes the PWM input of a lighting controller IC in the form of a current-based PWM signal to drive an external optocoupler. Apart from this PWM input option, no additional components are necessary.
