Dimming interface IC reduces component count by up to 70 percent
The CDM10V reduces the component count and PCB space needed for dimming circuitry in LED lighting applications by up to 70 percent. Infineon’s CDM10V is the industry’s first single-chip lighting interface IC 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 as 5 mA optocoupler-ready PWM signal with 0 to 100 percent 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 percent), 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 an ultra-miniature 6-pin SOT package, the CDM10V is ideally suited for use on small PCBs with high component densities. A supply voltage of 11 V to 25 V ensures compatibility with all common LED lighting applications including luminaires, troffers, downlights, sconces, office lighting and signage. The CDM10V joins a comprehensive portfolio of Infineon devices – including driver ICs and MOSFETs designed to simplify and speed the design of LED lighting applications.
Availability
Volume production of the Infineon CDM10V starts in April 2016 and engineering samples, a demoboard and a configuration board are all available now.
