LED power supply with current configuration using NFC-PWM IC
This evaluation board not only enables fast demonstration of NFC-PWM configuration ICs with NLM0011 through the NFC-PWM mobile app, but also accelerates the development of the NFC-reader software. EVAL_NLM0011_DC does not require a full system, but allows NFC configuration for existing LED driver boards.
The evaluation kit consists out of three boards: Two different NFC-boards including the NLM0011, and one demonstration board with LED display. The first NFC-board option is for single use with supply voltage from 5 to 25V. The second NFC-board is for single use with supply voltage from 3 to 5V. Both NFC-boards can be used together with the demonstration board, which indicates the set duty cycle from 0 to 80 percent by eight LEDs. With the NFC-PWM mobile app, the parameters (PWM frequency, duty cycle, operation hours, on/off counting, CLO table) of NLM0011 can be set.
For the boards DK_NLM_01 V1.0 02/19 and DK_NLM_02 V1.0 02/19 of the evaluation kit, we recommend to solder a 10pF tuning capacitor at the reserved C3 pad position for improved antenna coupling performance with some mobile phones.
