SP6852 Datasheet | SYNC POWER

DESCRIPTION The SP6852 is a low cost, low startup current, current mode PWM controller with green-mode power-saving operation. Built-in 700V MOSFET provides simple design for adapter. 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. The SP6852 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. SP6852 is available in DIP-8P package.
