austriamicrosystems Announces New Ultra Low Quiescent Current Step-Up DC-DC Converter

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 1µ=µA the AS1310 step-up converter also features the industry’s lowest quiescent current, operates over a wide 0.7 to 3.6V battery supply, and provides output voltages between 1.8 and 3.3V. 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 to 1.8V, 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. The features and performance of the AS1310 boost dc-dc converter make it very well suited for 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 an especially good fit for applications in which a lot of time is spent in an idle mode and therefore draws only a small current.
