DESCRIPTION
The ST8835 is low cost, 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 compensation. It would provide the users a superior AC/DC power application of higher efficiency, low external compotation of higher efficiency, low external component counts, and lower cost solution for applications.
