Austriamicrosystems AG announced the AS1321, a step-up DC-DC converter with a fully integrated synchronous rectifier. With a supply voltage of 1.5 to 5.0V the AS1321 is capable of delivering a 130mA output current at 2V input voltage. The converter features a shutdown mode where it draws less than 1µA. In this mode the battery is connected directly to the output to enable direct battery feed-through.
To ensure stable operation the integrated power on reset circuitry enables the AS1321 to reset any type of microprocessor after power up ensuring a stable start in all devices. The device is available in a SOT23-6pin package.
