NCL38046 Overview
Pin N5 Pin Name 1 FB 2 VDD 3 SET/REF 4 ADIM 5 PDIM 6 GND 7 CS 8 VS Pin Description Output of the feedback OTA. IC operating current is supplied to this pin At startup, external SET resistor and capacitor are detected to adjust the internal DIM modulator parameters. Then, 3.3 V output is provided for an external use such as setting ADIM voltage.
