1 / 13 page 2008/08/10 Ver.1 Page 1 SP6853 Green-Mode PWM Controller DESCRIPTION APPLICATIONS 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. AC/DC Switching Power Adaptor Battery Charger PC 5V Standby Power. Open-Frame Switching Power Supply FEATURES PIN CONFIGURATION SOT-23-6L DIP-8P PART MARKING SOT-23-6L DIP-8P High-Voltage BiCMOS Process Very Low Startup Current (<20µA) Under Voltage Lockout (UVLO ) Current Mode Control Non-audible-noise Green Mode Control Current Limiting LEB (Leading-Edge Blanking) on CS Pin OLP (Over Load Protection) OVP (Over Voltage Protection) on Vcc Pin Leading-Edge Blanking Programmable Switching Frequency Internal Slope Compensation Green-Mode Control for Power Saving 300mA Driving Capability |
