Product Type Package
CDM10V SOT23-6
Description
CDM10V is a fully integrated 0-10 V dimming interface IC and comes in a SOT-23-6 package to cover space
requirements on small PCBs.
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 potentiometer to the dimming or PWM input of a lighting
controller IC in the form of a 5 mA current based PWM signal to drive an external opto-coupler. It replaces many
components in a traditional solution and reduces BOM and PCB space significantly.
The CDM10V IC outputs a 0 - 100% PWM current signal at programmable frequency with an amplitude value of 5
mA.
The duty cycle of the PWM signal can be limited to a dedicated minimum value. Dim-to-o feature is supported
as well and can be enabled on demand.
Embedded digital signal processing maintains minimum variations from device to device.

3 Functional Description
Typical Application Circuit
Figure 2 Typical Application Circuit
Note: The Diode marked with * is for the protection of the R
dim+
-Pin when active dimming is used. This is
because the voltage on this Pin is not allowed to be higher than V
CC
+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 R
dim+
-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.
