目录7.相关产品 产品概述 返回TOP CXSD62298是高效同步，双通道PWM降压直流/直流转换器。在2.5 v的输入电压范围下工作5.5 v。它集成了两种PWM同步降压直流-直流转换器。The CXSD62298 is a high efficiency synchronous,dual channel PWM step-downDC/DC converter working under an input voltage range of 2.5V to 5.5V. It integratestwo PWM synchronous step-down DC-DC converters. 100% duty cycle capabilityextends battery life in portable devices,while the quiescent current (one channel) is200μA with no load, and drops to<1μA in shutdown.Each DC-DC converter hasindependent enable input and short-circuit protection allowing versatile powersequence combination.The CXSD62298 converters are available in the industrystandard DFN3*3-10L packages (or upon request).产品特点 返回TOP
