Austria Microsystem's new DC-DC boost converter delivers 42V

Austria Microsystems launched AS1343, a high voltage DC-DC boost converter optimized for LCD or OLED display bias from low voltage inputs of single cell battery powered applications. The new converter offers micro-power consumption with high efficiency while delivering high output voltages and currents.

The common features of AS1343 are listed below.

1. Can deliver 40mA at 24V from two AA cells or 30mA at 12V from a single AA cell and can provide adjustable output voltages in the range of 5.5 to 42V.
2. Operates from a single 0.9 to 3.6V supply.
3. The 1MHz fixed switching frequency minimizes the PCB footprint by allowing the use of tiny, low profile inductors and capacitors.
4. This constant frequency switching results in low, predictable output noise that can be easily filtered.
5. Offers an automatic power save operation, which improves the efficiency at light loads.
6. The low operating supply current of 22µA increases battery life in the application.
7. Offers a shutdown mode requiring less than 1µA current combined with an output disconnect feature.
8. Industrial temperature range of -40°C to +85°C.

Packaging: TDFN 10-pin package
Size: 3 x 3x 0.8mm
