Description
The SY20718E is a 5V adapter input with up to 18V surge bi-directional regulator which is designed for single cell Li-Ion battery power bank application. Advanced bi-directional energy flow control with automatic input power source detection is adopted to achieve battery charging mode and battery power supply mode alternately.
The SY20718E also integrates the discharging enable/disable control and LED status indication.
The SY20718E is available in QFN3x3 package to minimize the PCB layout size for wide portable applications.
Applications
- Single Cell Power Bank
- Portable Device with Single Cell Battery
