Datasheet Summary
300mA Step-Up DC-DC Converter
Data Sheet
1 General Description
The AS1325 is a high-efficiency step-up DC-DC converter designed to generate a fixed output voltage of +3.3V or +5V. The AS1325 achieves an efficiency of up to 96% and the minimum input voltage is 1.5V. The AS1325-BSTT-33 delivers up to 300mA output current at the fixed output voltage of +3.3V (@ 2V VBATT). With the fixed output voltage of +5V the AS1325-BSST-50 supplies up to 185mA output current (@ 2V VBATT). In order to save power the AS1325 Features a shutdown mode, where it draws less than 1µA. In shutdown mode the battery is connected directly to the output enabling the supply of real-time-clocks. The AS1325...
