The compact and highly integrated CDM10V dimming interface IC allows designers to replace many of the discrete components used in conventional 0–10V dimming schemes with a single device. Analog 0–10V 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 0–10V input into a PWM or dimming input signal required by a lighting controller IC.
The signal is delivered in the form of a 5mA optocoupler-ready 0 to 100% PWM output. One-time configuration of key parameters such as minimum duty cycle (1 to 10%), PWM output frequency (200Hz to 2kHz), dimmer/resistor bias current (50µA to 500µA) 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.
