- DESCRIPTION
- The AIC3417 is a high efficiency, step-up DC/DC converter with high light load efficiency. The true output disconnect function eliminates inrush current and allows 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 50mohm N-Ch MOSFET switch and a 60mohm P-Ch MOSFET switch; it can provide high efficiency at 1.0A continuous output current. High efficiency is achieved at light load when PSM Mode operation is entered, where the IC’s quiescent current is lower than 20uA on Vout. The AIC3417 is available in the small DFN-10 (3x3) and SOP-8E package.
