AS1325 pdf datasheet
分享资料个
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 provides a power-on reset output that goes high-impedance when the output reaches 90% of its regulation point.
The SHDNN trip threshold of the AS1325 can be used as an input voltage detector that disables the device when the battery voltage falls to a predetermined level.
An internal synchronous rectifier is included.
The AS1325 is available in a 6-pin SOT23 package声明：本文内容及配图由入驻作者撰写或者入驻合作网站授权转载。文章观点仅代表作者本人，不代表电子发烧友网立场。文章及其配图仅供工程师学习之用，如有内容侵权或者其他违规问题，请联系本站处理。 举报投诉
