Duty Cycle Package CDM10VD CDM10VD-2 CDM10VD-3 CDM10VD-4 5 mA / 5 % 5 mA / 10 % 1 mA / 5 % 1 mA / 10 % SOT23-6 SOT23-6 SOT23-6 SOT23-6 Description CDM10V is a fully integrated 0-10 V dimming interface IC and comes in a SOT23-6 package to cover space requirements on small PCB designs. The device is targeted for various dimming applications in lighting. The IC can be used to transmit analog voltage based signals from a 0-10 V dimmer or a potentiometer or a PWM input of a lighting controller IC, transformed to a 5 mA/1 mA current based fixed frequency PWM signal, to directly drive an external optocoupler. To avoid flickering when dimming, the light up and the light down threshold has a minimum implemented hysteresis of 200mV. It replaces many components in a traditional solution and reduces BOM and PCB space significantly. The CDM10VD-Series ICs outputs a 0 - 100% PWM current signal at a frequency of 1 kHz with an amplitude value of 1mA or 5 mA.

This is because the voltage on this Pin is not allowed to be higher than VCC+0.5V. It is advised to use a low leakage, low reverse current Schottky-Diode in order to not influence the dimming performance (e.g. MMSD301T1G). Note: The capacitor connected to the Rdim+-Pin reduces the amount of coupled noise to the dimming signal. The size of this capacitance should be in the range of 2.2 - 10 nF (typ. 4.7 nF), where a small capacitor allows steeper edges of the dimming signal, a larger capacitor enhances the noise reduction.
