SP6853-Green-Mode PWM Controller DataSheet

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 compensation. It would
provide the users a superior AC/DC power application of higher efficiency, low external component counts, and lower cost solution for applications.
The SP6853 features more protections or functions for the following characteristics :
※Add OLP (Over Load Protection) function to provide better protection performance for fault conditions like short circuit or over load.
※Modify the OVP (Over Voltage Protection) mechanism from the cycle-by-cycle mode to the hiccup mode.
    SP6853 is available by SOT-23-6L / DIP-8P packages.
