Press Release Summary:
Manufactured in 6-pin SOT23 package, AS1320 features fully integrated synchronous rectifier that eliminates need for external transistors. Unit operates from 1.5-3.5 V supply voltage and draws less than 1 µA in shutdown mode, which enables input battery to be used as backup or real-time clock supply when converter is off. Product, capable of delivering 200 mA output current at 3.3 V fixed output voltage, has 90% efficiency rating.
Original Press Release:
austriamicrosystems Introduces 200mA Step-Up DC-DC Converter
AS1320 high efficiency step-up DC-DC converter supplies fixed output of 3.3V for battery powered applications where smallest size and lowest power consumption are critical
RALEIGH, N.C. (November 28, 2005) - 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 to 3.5V the AS1320 is capable of delivering a 200mA output current at a 3.3V fixed output voltage. With an efficiency of 90% the AS1320 is an ideal solution for battery powered portable applications.
The AS1320 features a shutdown mode where it draws less than 1µA. In shutdown mode the battery is connected directly to the output to enable direct battery feed through. This enables the input battery to be used as backup or as a real-time clock supply when the converter is off and eliminates the need for an expensive back-up battery. To ensure stable operation the integrated power on reset circuitry enables the AS1320 to reset any type of microprocessor after power up.
The high output current combined with the low power consumption makes the AS1320 an ideal solution for battery powered devices like medical and diagnostics devices, digital cameras, PDA's and smart phones, cordless phones and other handheld products. In particular, dual-cell powered battery devices benefit from the AS1320.
The AS1320 is available in a SOT23-6pin package without the need for external components and is pin compatible to Maxim MAX1833 and the MAX8569B.
