VCC1 Supply Input 1: 15V to 25V supply. It is automatically selected when VO = 13V

VCC2 Supply Input 2: 22V to 25V supply. It is automatically selected when VO = 18V

OUTPUT Regulator output. It is 13V typ. when VSEL LOW and 18V typ. when VSEL HIGH

GND GROUND

VSEL Output Voltage Selection: Logic Control Input; if LOW VO = 13V, when HIGH VO = 18V

ENABLE Logic Control Input; force LOW to put the IC in shutdown

TONE Logic Control Input; force HIGH to activate the internal 22KHz tone

EXTM

External Modulation: Needs DC decoupling to the AC source. If not used can be left
