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.
Datasheet
Please read the Important Notice and Warnings at the end of this document V1.1
www.infineon.com 2017-08-02
The duty cycle of the PWM signal can be selected to be either 5% or 10%. Dim-to-o feature is fully supported
with a minimum hysteresis of 200 mV between dim-to-dark and dim-to-light.
Embedded digital signal processing maintains minimum variations from device to device.
