 DESCRIPTION
The AIC3417 is a high efficiency, step-up DC/DC con-
verter with high light load efficiency. The true output
disconnect function eliminates inrush current and al-
lows Vout to go to zero during shutdown.
The AIC3417 is suited for high current boost application
such as battery backup supplies or wireless devices
powered by one Li-Ion battery or two Alkaline, Ni-Cd,
Ni-MH battery.
The device includes a 50mΩ N-Ch MOSFET switch
and a 60mΩ P-Ch MOSFET switch; it can provide high
efficiency at 1.0A continuous output current. High effi-
ciency is achieved at light load when PSM Mode oper-
ation is entered, where the IC’s quiescent current is
lower than 20μA on Vout.
The AIC3417 is available in the small 3mm x 3mm
DFN-10 and SOP-8(EP) package.
