1 / 16 page  AS1331 300mA Buck-Boost Synchronous DC/DC Converters www.austriamicrosystems.com Revision 1.03 1 - 16 Datasheet 1 General Description 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/NiCad/NiMH as well as single cell Li-Ion battery applications. Because of the implemented Power Save Mode, the solution footprint and the component count is minimized and also over a wide range of load currents a high conversion efficiency is provided. The device includes two N-channel MOSFET switches and two P-channel switches. Also following 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 ! Input Voltage Range: 1.8V to 5.5V ! Output Voltages: - Fixed: 2.5V, 3.0V, 3.3V - Adjustable: 2.5V to 3.3V ! Output Current: 300mA @ 3.3V ! Up to 90% efficiency ! Power Good ! Output Disconnection in Shutdown ! Automatic transition between Buck and Boost mode ! Ultra Low Quiescent Current: 22µA, Shutdown Cur- rent <1µA (Active Low) ! Short-Circuit Protection ! Low Battery detection ! Over Temperature Protection ! 10-pin 3x3mm TDFN package 3 Applications The AS1331 is an ideal solution for handheld computers, handheld instruments, portable music players and PDA’s. Two and three cell Alkaline, NiCd or NiMH or single cell Li battery powered products. Figure 1.
