Description CDM10V-4 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-4 IC outputs a 0 - 100% PWM current signal at 2 kHz with an amplitude value of 5 mA. Embedded digital signal processing maintains minimum variations from device to device.

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. Recommended cooling area In order to guarantee the full functionality of the CDM10V-4 device, the required cooling area has to be selected according to the graph in Figure 3.

Also valid if VCC is 0 V. Absolute maximum ratings (Table 3) are defined as ratings which when being exceeded may lead to destruction of the integrated circuit. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Maximum ratings are absolute ratings; exceeding only one of these values may cause irreversible damage to the integrated circuit. These values are not tested during production test.
