6. ONOFF1, 2 Input Operation
As Figure 6 shows, when the ONOFF1 terminal (pin 9) goes from “L” level to “H” level, the VCONT terminal (pin
16) goes to “H” level, and the OUT1 (pin 29), OUT2 (pin 30), OUT3 (pin 27), and OUT4 (pin 22) terminals output
their respective regulated voltages.
The next time the POFF terminal (pin 18) goes from “L” level to “H” level, the VCONT terminal (pin 16) goes to
“L” level, and the OUT1 (pin 29), OUT2 (pin 30), and OUT4 (pin 22) terminals go to “L” level. Then when the
ONOFF2 terminal (pin 17) goes from “L” level to “H” level, the VCONT terminal returns to “H” level, and the
OUT1, OUT2, OUT3 and OUT4 terminals output their respective regulated voltages.
The next time the POFF terminal goes from “L” level to “H” level, the VCONT terminal goes to “L” level, and the
OUT1, OUT2, and OUT4 terminals go to “L” level. Then when the ONOFF1 terminal goes from “L” level to “H”
level, the VCONT terminal returns to “H” level, and the OUT1, OUT2 and OUT4 terminals output their respective
regulated voltages.
The next time the POFF terminal goes from “L” level to “H” level, the VCONT terminal goes to “L” level, and the
OUT1, OUT2, and OUT4 terminals go to “L” level. Then when the ONOFF2 terminal goes from “H” level to “L”
level, the VCONT terminal returns to “H” level, and the OUT1, OUT2 and OUT4 terminals output their respective
regulated voltages.
The next time the POFF terminal goes from “L” level to “H” level, the VCONT terminal goes to “L” level, and the
OUT1, OUT2, and OUT4 terminals go to “L” level.
