• Ripple: 50mA (max)
• Noise: 100mV (max)
• OVP: 3.3-5.0V
• Short-circuit protection
• Fuse protection
• *Ripple(max)=75mV when regulate in IDLE mode

• Ripple: 300mV (max)
• Noise: 500mV (max)
• OVP: 7-9 V
• *The +6V max load condition is available only when the +5V output load is greater than
0.5A.
• 5VSB:Load : 5mA Regulation:+/-10%
• Ripple: 75mV(max) Noise: 250mV(max)
• P.G. :Active high within 100ms to 500ms after system’s +5V, 3.3V and Vcpu are all in
regulation.
• Driving capability:12uA(source) 200uA(sink)
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.
