AS1331 Datasheet (austriamicrosystems AG) - 300mA Buck-Boost Synchronous DC/DC Converters

AS1331, 300mA Buck-Boost Synchronous DC/DC Converters

This special device is a synchronous buck-boost DC/DC converter which can handle input voltages above, below, or equal to the output voltage.

Due to the internal structure of the AS1331 which is working continuously through all operation modes this device is ideal for dual or triple cell alkaline/Ni

AS1331 Features

* are implemented: a quiescent current of typically 22µA (ideal for battery power applications), a shutdown current less than 1µA, current limiting, thermal shutdown and output disconnect. The AS1331 is available in a 10-pin 3x3mm TDFN package with fixed and adjustable output voltage. 2 Key Features
