Brief Description
The KTC2110A features a high-efficiency, micropower synchronous boost for Lithium-Ion/Polymer battery applications.
The KTC2110A achieves high efficiency over a wide output current range by operating in auto PWM/PFM control. The control method is automatically selected according to the output load conditions.
The KTC2110A also features Bypass Mode which allows passing input power directly to output with over current protection when EN pin is pulled LOW.
