Description
ST8835
Green-Mode PWM Controller
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. The ST8835 features more protections or functions for the following characteristics∶ ☆Add OLP (Over Load Protection) function to provide better protection performance for fault conditions the OVP ( Over Voltage Protection ) mechanism form the cycle-by-cycle mode to the hiccup mode. ST6853 is available by SOT-23-6L / DIP-8P packages.
