Know about the Technology behind Batteroo

HOW DOES WORK

The voltage from the battery starts to go down when the battery-operated device start working and extracting energy from the battery. In case of active load devices such as digital cameras, device stops operating when the battery voltage drops below a pre-determined cut off voltage. Batteroo Boost circuitry generates a voltage that is higher than the cut off voltage until the battery energy is depleted and consequently extending the operating life of the device by tapping into the energy that would have otherwise been throw away. The Batteroo Boost is a high efficiency, fixed interleaved frequency 1.4MHz, current mode PWM boost DC/DC converter which could operate from single-cell NiCd, NiMH or alkaline battery such as input voltage below 0.6V. The converter output voltage is adjusted from 1.5V to 1.32V from VIN at 1.5V to .80V. No external Schottky diode is required and the converter can achieve efficiency 95%. Which Increases battery life up to 600%.

The converter switches automatically into burst mode at light load with quiescent current on only 15uA. When converter operates into discontinuous mode, the internal anti-ringing switch could reduce interference and radiated electromagnetic energy.
