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-down
DC/DC converter working under an input voltage range of 2.5V to 5.5V. It integrates
two PWM synchronous step-down DC-DC converters. 100% duty cycle capability
extends battery life in portable devices,while the quiescent current (one channel) is
200μA with no load, and drops to<1μA in shutdown.Each DC-DC converter has
independent enable input and short-circuit protection allowing versatile power
sequence combination.The CXSD62298 converters are available in the industry
standard DFN3*3-10L packages (or upon request).
