产品概述 返回TOP
The CXSD62337 is highly efficient with peak efficiency at 91% when in operation. In shutdown mode the regulator draws less than 18μA of supply current. Protection features include cycle-by-cycle current limit and thermal shutdown. The device also includes an internal soft-start and an external adjustable soft-start function to limit the inrush current and prevent the overshoot of output voltage.
The CXSD62337 is available in Green SOIC-8 (Exposed Pad) package and requires a minimum number of readily available external components to complete a 3A step-down DC/DC converter solution.
