一.产品概述

---

    The CXSD6272 is a high efficiency, synchronous step down DC-DC convertor optimized for battery powered portable applications. It supports up to 2A continuous 3A peak output current. With a wide input voltage range of 3V 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. 

     The CXSD6272 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. 

     The CXSD6272 is available in SOT-23-5L and SOT-23-6L package. Standard product is Pb-free and Halogen -free.
