NFC LED Driver

Product Description

Infinity AdaptLED 33w 350-750mA 33w NFC LED Driver

The Infinity AdaptLED Driver currently comes in a 33w version and a 45w version.

This product has a NFC/CLO dual-mode NFC configuration IC chip with pulse width modulation (PWM) output, it was designed for LED applications to enable the emerging NFC programming feature, which is compatible with the Module-Driver Interface Special Interest Group (MD-SIG).

Summary of Features
•     Configurable pulse width modulation (PWM) output
•     NFC contactless interface compliant to ISO/IEC 18000-3 mode 1 (ISO/IEC 15693)
•     Constant light output (CLO) with 8 configurable points
•     Integrated operation time counter (OTC) and on/off counter
•     Non-volatile memory (NVM) including UID and 20 bytes free memory for user data Benefits
•     Fast and cost-effective implementation of NFC-programming and CLO without the need of an additional microcontroller
•     Compatible with existing analogue LED driver designs using plug-in-resistor method
•     Stable PWM output with fixed 2.8V amplitude and +/- 0.1% duty cycle accuracy
•     Internal low-dropout voltage regulator (LDO) to avoid influence of instable external supply voltage
•     Compatible with the MD-SIG NFC-programming specification

In addition, advanced features such as the constant lumen output (CLO) as well as the on/off counting are integrated, and there is no need for an additional microcontroller. Since the NFC/CLO is designed to work together with mainstream analogue driver ICs, there are no firmware development 
efforts are needed. It can be easily adapted into existing designs to replace the “plug-in resistor” current configuration concept. The NFC/CLO operates in two operating modes: passive and active mode.

In the passive mode, where no VCC voltage supply is applied, PWM parameters can be configured wirelessly via the NFC interface/ also be via an App once we have the funds to finish the building of the platform. In active mode, as soon as the VCC voltage supply is applied, a PWM output is generated according to the stored PWM parameters. With an external R/C filter, the PWM signal is converted to the desired DC voltage to control the current output of the LED driver. With an integrated operation-time counter and the LED degradation curve stored le, the PWM signal is automatically adjusted to compensate for the LED degradation.
