SP6878-Quasi-Resonant PWM Controller DataSheet
The SP6878 is a low cost, quasi-resonant flyback controller where the maximum frequency is below 100KHz. The internal valley detector ensures the converter operates at quasi-resonant operation over wide range of line voltage. To reduce the standby power loss and increase the efficiency at light load, a proprietary burst mode design is applied. 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 SP6878 features more protections or functions for the following characteristics: over voltage protection (OVP); over temperature protection (OTP); over load protection (OLP). SP6878 is available by SOP-8/ DIP-8P packages.
