Dimming interface IC save up to 70% component count and board space
According to the company, it can reduce the component count and PCB space needed for dimming circuitry in LED lighting applications by up to 70%. It is, says the company, the industry’s first single-chip lighting interface IC capable of transforming an analogue 0 to 10V input into a PWM or dimming input signal required by a lighting controller IC. The signal is delivered as 5mA optocoupler-ready PWM signal with 0 to 100% duty cycle.

It can be used across a variety of different commercial and industrial LED lighting applications, using a one-time configuration of key parameters such as minimum duty cycle (one to 10%t), PWM output frequency (200Hz to 2kHz), dimmer/resistor bias current (50 to 500μA) and ‘dim-to-off’ functionality. Furthermore, with ‘dim-to-off’ enabled the IC also provides the option of accepting PWM input signals.

It is supplied in a miniature, 6pin SOT package, for use on small PCBs with high component densities. A supply voltage of 11 to 25V means compatibility with all common LED lighting applications, including luminaires, troffers, downlights, sconces, office lighting and signage.

Engineering samples, a demoboard and a configuration board are available now.
