Pin Function Description
Charge pump cap.
generate high voltage from standby power.
Charge pump switcher.
3.3V SDRAM gate control.
from the 3.3V main supply.
3.3V SDRAM voltage feedback.
feedback control loop for 3.3V SDRAM, and also sources 3.3V SDRAM in
standby.
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 8 is used as the input for the voltage feedback
control loop for 3.3V dual.
Power Good.
Open collector output is high when all outputs are valid.
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.
PWROK.
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.
2.5V feedback.
Pin 15 is used as the input for the voltage feedback control loop for
2.5V dual (RAMBUS), and also sources 2.5V dual in standby.
2.5V base drive control.
Attach this pin to an NPN transistor powering 2.5V dual
(RAMBUS) from the 3.3V main supply.
5V Voltage Feedback.
Pin 17 is used to sense undervoltage to protect the 5V dual
from overcurrent.
5V standby gate control.
Attach this pin to a transistor powering 5V dual from the
5V standby supply.
5V main gate control.
Attach this pin to a transistor powering 5V dual from the 5V
main supply.
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
