NLM001x: Worst case tolerance of generated DC voltage
With the integrated voltage regulator, every NLM001x provides a very stable PWM signal. Neverthless, like any products, a chip-to-chip variation caused by the manufacturing process is unavoidable. Please read the chapter 7.2 in the application note to learn the tolerance level estimation.
One big advantage of NFC interface is the simple and fast reconfiguration possibility. With so-called in-production calibration, the product overall tolerance (not a simple component, but the whole system) can be minimized by calibrating the control voltage, adjusting the PWM duty cycle. By doing that, the product tolerance level can be significant reduced and even the tolerance requirement of individual components can be relaxed.
