It is, Infineon says, the first single-chip lighting interface IC capable of transforming an analogue 0-10V input into a PWM or dimming input signal required by a lighting controller IC. The signal is delivered as 5 mA optocoupler-ready PWM signal with 0 to 100% duty cycle.
The CDM10V can be used across a variety of different commercial and industrial LED lighting applications. This is enabled by one-time configuration of key parameters such as minimum duty cycle (1 to 10%), PWM output frequency (200 Hz to 2 kHz), dimmer/resistor bias current (50 μA to 500 μA) and ‘dim-to-off’ functionality. Furthermore, with ‘dim-to-off’ enabled the IC also provides the option of accepting PWM input signals.
Supplied in a 6-pin SOT package, the CDM10V is suited for use on small PCBs with high component densities. A supply voltage of 11 to 25V ensures compatibility with all common LED lighting applications including luminaires, troffers, downlights, sconces, office lighting and signage.
