ON Semiconductor Is Now
www.onsemi.comcurrent is sensed at negative DC output line as a voltage drop over 300 shunt, amplified by special current sensing amplifier NCS210. Since controller board sits on secondary side, primary side input voltage information has to be insulated in reasonable way. Simple voltage to current converter at primary side is
