Brief Description
The KTC2110 features a high-efficiency, micropower synchronous boost for Lithium-Ion/Polymer battery applications. It offers true output disconnect to achieve a shutdown quiescent current of less than 1.0µA, extending battery life.
High efficiency over a wide output current range is achieved by selecting PWM/PFM mode automatically depending on the output load conditions.
A Pass Through mode allows to transfer the input power directly to output (not boosting) with over current protection.
