Spotlight on Digital Power
Austriamicrosystems has launched the AS1320, a high-efficiency step-up dc-dc converter with fully integrated synchronous rectifier, eliminating the need for external transistors. With a supply voltage of 1.5 V to 3.5 V, the AS1320 is capable of delivering a 200 mA output current at a 3.3-V fixed output voltage. Conversion efficiency is 90%. The high output current combined with the low power consumption makes the AS1320 a suitable solution for battery-powered devices
The AS1320 features a shutdown mode where it draws less than 1 µA. In shutdown 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 AS1320 to reset any type of microprocessor after power up.
The AS1320 is available in a SOT23 6-pin package without the need for external components and is pin compatible to the Maxim MAX1833 and the MAX8569B.
