2.10.4 Control
•
VCPU Control: Control switch can switch Vcpu output voltage to 2.35V2.45V2.9 or 3.1V.
•
ON/OFF: A logic low will turn off +5V,+3.3V, 2.35V/2.45V/2.9V/3.1V,+12V and +6V
main o/p. The DC/DC converter draws about 30uA when the notebook computer is in
shutdown mode.
2.10.5 Application:
Input filter capacitor
The recommended value is two pieces of 10uf/50V ceramic capacitor(or the same grade
capacitor, such as SANYO OS-CON capacitor) with less than 150mohm ESR. And it should be
located less than 10mm away from DCBATT_IN pin.
