Pin Function Description
Charge pump cap.
generate high voltage from standby power.
Charge pump switcher.
5V Standby.
Apply +5V standby on this pin to run the circuit in standby mode.
3.3V main gate control.
Attach this pin to a transistor powering 3.3V dual from
the 3.3V main supply.
3.3V standby gate control.
Attach this pin to a transistor powering 3.3V dual
from the 5V standby supply.
3.3V voltage Feedback.
Pin 6 is used as the input for the voltage feedback
control loop for 3.3V dual.
SLP_S3.
Control signal governing the Soft Off state S3. Internal current source
pulls this line high if left open.
SLP_S5.
Control signal governing the Soft Off state S5. Internal current source
pulls this line high if left open.
PWR_OK.
Control signal for switches. Internal current source pulls this line high if
left open.
Softstart.
Attach a capacitor to this pin to determine the softstart rate.
Ground.
Connect this pin to ground.
Adjustable Dual Voltage Feedback.
Pin 12 is used as the input for the voltage
feedback loop for the adjustable dual voltage.
Adjustable Dual Voltage
. Pin 13 sources VADJ during standby.
Adjustable Dual Voltage Base Control.
Attach this pin to an NPN transistor
powering VADJ from the 5V Main.
5V Main.
Apply +5V Main on this pin to run the VADJ base drive.
Main Power.
Apply +12V through a diode on this pin to run the circuit in normal
mode. Bypass with a 0.1μF capacitor. When 12V is not present, this pin produces
voltage doubled 5V standby.
Attach flying capacitor between this pin and PUMP to
