austriamicrosystems has expanded its inductorless boost converter portfolio with the AS1302, a small inductorless DC-DC boost converter.
It is capable of output currents as high as 30 mA from a wide input range of 2,9 to 5,15 V.
The new IC 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 1,2 MHz switching frequency allows the use of very small external capacitors. To improve efficiency, the frequency is reduced to 49 kHz during light load conditions. The device requires only two 220 nF flying caps and two 2,2 μF bypass capacitors.
Providing a regulated output, the AS1302 is ideally suited for a variety of applications such as 2-3 AA cells alkaline/NiMH or 1 cell Li-Ion battery to 5 V boost conversion in portable devices. With efficiency of up to 99% in 1:1 mode and up to 90% in 1:2 or 2:3 mode, the device offers low quiescent current and features a 10 nA shutdown mode in which the output is fully disconnected from the input.
To prevent excessive inrush current during startup, the AS1302 offers a soft-start feature plus additional features like overload protection and thermal shutdown circuitry. It is available in a 1,2 x 1,2 mm WL-CSP 8-bump package and is suitable for operating environments ranging from -40°C to +85°C.
