CDM10V Product Brief

Product Brief
CDM10V
0–10 V dimming interface IC
The compact and highly integrated CDM10V allows designers to replace many of the discrete components used in conventional 0–10 V dimming schemes with a single device.
Analog 0–10 V to digital PWM converter for dimming
Infineon’s CDM10V is the industry’s first single-chip lighting interface IC dedicated for
lighting applications capable of transforming an analog 0–10 V input into a PWM or dimming input signal required by a lighting controller IC. The signal is delivered in the form
of a 5 mA optocoupler-ready 0 to 100 percent PWM output. One-time configuration of key
parameters such as minimum duty cycle (1 to 10 percent), PWM output frequency (200 Hz
to 2 kHz), dimmer/resistor bias current (50 µA to 500 µA) and “Dim-to-Off” functionality
allows the CDM10V to be used across a variety of different commercial and industrial LED
lighting applications. Furthermore, with “Dim-to-Off” enabled the IC also provides the
option of accepting PWM input signals.
High level of integration, achieving low BOM cost
Supplied in an ultra-miniature 6-pin SOT package, the CDM10V is ideally
suited for use on small PCBs with high component densities. Beside
the optocoupler, no additional components are needed to realize the
analog to PWM conversion.

Key benefits
Supporting wide range of supply power
A supply voltage of 11 V to 25 V ensures compatibility with all common
LED lighting applications including luminaries, troffers, downlights,
sconces, office lighting and signage.
Configurable
To configure CDM10V, eFuses are used which can be one time burned to
set the desired parameters. This allows adaptions to different application
requirements. The device is coming with default settings. The configuration is easy to understand. One byte will be sent to the UART interface.
An optional configuration board is available to perform the configuration.
