NAME

FUNCTION

1VCC1

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

2VCC2

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

4GND

GROUND

5VSEL

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

7 (LNBP9)

TONE

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

7 (LNBP8)

EXTM

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