一,产品概述(General Description)
The CXSD6131 is a fully integrated, high– efficiency 2A synchronous rectified
step-down converter. The CXSD6131 operates at high efficiency over a wide output
current load range.This device offers two operation modes, PWM
control and PFM Mode switching control, which allows a high efficiency over
the wider range of the load.
The CXSD6131 requires a minimum number of readily available
standard external components and is available in a 6-pin SOT23 ROHS compliant package.
