Kinetic Technologies KTC2110 Low IQ Synchronous Boost Converter

Kinetic KTC2110 Low I_Q Synchronous Boost Converter 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 the user to transfer the input power directly to the output (not boosting) with over-current protection.

The constant on-time design does not require any external compensation components, simplifying the design and providing an ultra-fast transient response. The inrush current-limiting feature minimizes the voltage droop on the battery supply when the device is turned on. The Kinetic KTC2110 is packaged in an advanced RoHS and Green compliant 1.38mm x 1.38mm 9-ball Wafer-Level Chip-Scale Package (WLCSP).
