SP6878
Quasi-Resonant PWM Controller
DESCRIPTION
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. The build-in advanced
energy saving function 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.
