Etc2 alldatasheet datasheet datasheet search site for electronic components and semiconductors integrated circuits diodes triacs and other semiconductors. The rs resistor is calculated using this formula. The pt4115 includes the power switch and a high side output current sensing circuit which uses an external resistor to set the nominal average output current and a dedicated dim input accepts either a dc voltage or a wide range of pulsed dimming.
