General Description
SY6926 is a 4.1-6.5VIN up to 18VINsurge bi-directional regulator 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. If the external power supply is present, SY6926 runs in battery
charging mode with fully protection function; if the external power supply is absent, SY6926
runs in battery power supply mode with output current capability up to 2.5A.
SY6926 has an integrated reverse blocking switch to prevent current leaking from the system
side or battery side to the input side and an integrated linear switch to achieve over voltage/
current protection at the system side. A half bridge with 1MHz switching frequency is integrated
to achieve power conversion for battery charging mode and battery power supply mode. All of
them adopt N-channel MOSFETs with 18V rating and extremely low RDS(ON) to optimize
operation efficiency and extend battery life-time. SY6926 is available in QFN4x4 package to
minimize the PCB layout size for wide portable applications.
