Application Notes: AN_SY6990 Wide Input, High current, Bi-directional Regulator for Single Cell Li-Ion Battery Power Bank Application Advanced Design Specification General Description SY6990 is a 4.0-13.5V input, bi-directional regulator for 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. If the external power supply is present, SY6990 runs in battery charging mode with fully protection function. If the external power supply is absent, SY6990 runs in battery power supply mode with output current capability up to 3A.
