2. Delayed ON Input Operation (XON)
As Figure 2 shows, When the XON terminal (pin 11) changes from “H” to “L” level, the capacitor connected to
the RC1 terminal (pin 15) starts to charge. After the delay interval (t
XON
: 600ms (Typ.)), once the RC1 terminal
exceeds the internal threshold voltage 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 then output their respective regulated voltages after
a delay interval (t
R1
). Note however that for the OUT3 terminal to output its regulated voltage, it is necessary for
the CONT2 terminal (pin 26) to be at “L” level. Also, for the XON pin to return from “L” level to “H” level, a delay
interval (t
XON
: 600 ms (Typ.)) is required.
3. CONT1 Input Operation
As Figure 3 shows, when the CONT1 terminal (pin 14) goes from “H” to “L” 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 then output
their respective regulated voltages after a delay interval (t
R1
). Note however that for the OUT3 terminal to output
its regulated voltage, it is necessary for the CONT2 terminal (pin 26) to be at “L” level. Also once the OUT1,
OUT2, OUT3, and OUT4 terminals have started to output their regulated voltages, the voltage at the OUT1,
OUT2, OUT3, and OUT4 terminals will not change even if the CONT1 terminal goes from “L” to “H” level, or
from “H” level to “L” level.
