austriamicrosystems introduces high efficiency inductorless DC-DC boost converter
austriamicrosystems (SWX: AMS), a leading global designer and manufacturer of analog ICs for communications, industrial, medical and automotive applications has introduced the AS1301, the first inductorless DC-DC boost converter in an upcoming portfolio. The AS1301 is capable of output currents as high as 50mA from a wide ranging input of 2.7 to 5.25V.
AS1301 delivers 50mA at 5V while requiring smallest external components
The new AS1301 offers low-noise constant frequency operation from light to higher loads. Its unique constant-frequency architecture provides both low input and low output ripple and its high 1MHz switching frequency allows the use of extremely small external capacitors. The AS1301 is an extremely compact solution for space-constrained applications.
Providing a regulated output, the AS1301 is ideally suited for a variety of applications such as 2-3 AA cells alkaline/NiMH or 1 cell Li-Ion battery to 5V boost conversion in portable devices. With an excellent efficiency of up to 92%, the AS1301 offers lowest quiescent current and features a
