austriamicrosystems has introduced the AS1310, an ultra low quiescent current hysteretic step-up DC-DC converter optimized for light loads (60mA) and the highest efficiency – up to 92 %. With 1 µA the AS1310 step-up converter also features the industry’s lowest quiescent current, operates over a wide 0.7 V to 3.6 V battery supply, and provides output voltages between 1.8 V and 3.3 V. Even at loads as light as 100 µA, efficiency still reaches 85%, significantly increasing battery life.
Since the supply voltage of many battery powered applications is moving from 3 V to 1.8 V, the AS1310 boost DC-DC converter was designed to be able to generate both; many competitive DC-DC converters are not able to do so. If the input voltage exceeds the output voltage the device goes into a feed-through mode and the input is directly connected to the output voltage.
Applications include single- and dual-cell powered devices, including blood glucose meters, remote controls, hearing aids, wireless mouse or any light-load application. The AS1310 DC-DC converter is also a good fit for applications in which a lot of time is spent in an idle mode and therefore draws only a small current.
