一.产品概述GWy嘉泰姆

     The CXSD6270 is a high efficiency, synchronous step down DC-DC converter optimized for battery powered portable applications. It supports up to 1.2A 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. The CXSD6270 operates at 1.5MHz 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. GWy嘉泰姆

    The switching frequency is internally set at 1.5MHz, allowing the use of tiny surface mount inductor and input/output capacitors. Low output voltage is easily supported with the 0.6V feedback reference voltage.        GWy嘉泰姆

    The CXSD6270 is available in SOT-23-5L package. Standard product is Pb-free and Halogen-free. GWy嘉泰姆
