描述

The DIO8269 is a dimming interface converter that can recognize its input signal, which can be a 0/1~10 V dimming, resistor, or PWM signal. To achieve isolated dimming, the final output of the DIO8269, which is a PWM signal, is used to control a dimmable CC regulator or drive an opto-coupler. The frequency of the source current and output PWM signal to drive passive 0 ~ 10 V dimmer/resistor can be set by an external capacitor and resistor.
