The AS1301 is a 50mA inductorless boost converter using a double H-bridge charge-pump topology with two small (≤220nF) external flying capacitors.
The AS1301 runs on a 1MHz fixed frequency and is utilized with a low noise regulation scheme to allow usage together with sensitive RF circuitry from the same battery supply.
Designed to reside in portable and space limited equipment the 1MHz charge pump converts a 2.7 to 5.25V input to regulated 5V output with 5% accuracy.
The shutdown function reduces the supply current to <5μA and disconnects the load from the output. The integrated soft-start circuitry prevents current spikes being drawn from the battery during start-up.
The AS1301 is available in TDFN (3x3x0.8mm) 10-pin and WL-CSP 8-bumps packages.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
