Figure 1 NLM0011 Application View
The NLM0011/NLM0010 chip is connected to the LED driver circuit. The driver circuit controls the current of the LEDs. The setpoint value of the current is stored in integrated NVM of the NLM0011/NLM0010. According to the NVM content the NLM0011/NLM0010 generates a PWM output, which corresponds to the value of the setpoint. Usually the PWM data pulses are converted into an analog voltage by an external R/C circuitry. This analog voltage is the reference setpoint for the LED current regulation loop of the module. The analog value of the setpoint is determined by the period and duty cycle of the PWM output, the time constant of the R/C circuitry and the voltage swing of the PWM output driver. The NLM0011/NLM0010 provides only the setpoint definition of the LED current of the regulation loop. The NLM0011/NLM0010 does not execute the regulation loop or any parts of the regulation loop. Within LED lighting systems the setpoint definition is usually called "ISET". Some LED drivers/ controller accept the direct PWM input and convert the PWM data into a setpoint value internally. In that case no R/C circuitry is needed between the NLM0011 /NLM0010 and the LED driver.
