[ AP2200]
AP2200
Step-up DC/DC converter IC supporting 1 or 2 solar cells
OVERVIEW
The AP2200 is a voltage step-up DC/DC converter using the synchronous rectification method to
be activated with 1 or 2 solar cells and is ideal for charging lithium-ion batteries or outputting USB
VBUS voltage. Also, the MPPT (Max Power Point Tracking) function is embedded in order to
maximize the output power from the solar cells.
