SP6853 Description
The SP6853 is a low cost , low startup current , current mode PWM controller with green-mode power-saving operation. The integrated functions include the leading-edge blanking of the current sensing, internal slope pensation. It would provide the users a superior AC/DC power application of higher efficiency, low external ponent counts, and lower cost solution for applications.
