目录 1.产品概述 2.产品特点 一,产品概述(General Description) The CXSD61040D is a 1.5MHz constant frequency,current mode step-down converter. It is ideal for portable equipment requiring very high current up to 2A from single-cell Lithium-ion batteries while still achieving over 90% efficiency during peak load conditions. The CXSD61040D also can run at 100% duty cycle for low dropout operation, extending battery life in portable systems while light load operation provides very low output ripple for noise sensitive applications. The CXSD61040D can supply up to 2A output load current from a 2.3V to 6V input voltage and the output voltage can be regulated as low as 0.6V. The high switching frequency minimizes the size of external components while keeping switching losses low. The internal slope compensation setting allows the device to operatewith smaller inductor values to optimize size and provide efficient operation. The device is available in a Pb-free, 3x3mm 10-lead DFN package and is rated over the -40°C to +85°C temperature range.This device offers two operation modes, efficiency over the wider range of the load. 二.产品特点(Features) High Efficiency: Up to 96%
