一.产品概述DKE嘉泰姆


   The CXSD6271 is a high efficiency, synchronous step down DC-DC convertor optimized for battery powered portable applications. It supports up to 2A continuous 2.5A peak output current. With a wide input voltage range of 2.7V to 5.5V, the device supports applications powered by single Li-ion battery with extended voltage range, two and three alkaline cell, 3.3V and 5V input voltage range. DKE嘉泰姆

    The CXSD6271 operates at 1MHz fixed switching frequency with Pulse-Width-Modulation (PWM) and enters Pulse-Skipping-Modulation (PSM) operation at light load current to maintain high efficiency over the entire load current range. 100% duty cycle capability provides low dropout operation, extending battery life in portable systems. The switching frequency is internally set at 1MHz, allowing the use of tiny surface mount inductor and input/output capacitors. DKE嘉泰姆

     The CXSD6271 is available in SOT-23-5L package. Standard product is Pb-free and Halogen -free. DKE嘉泰姆
