SP6878

功能特点

产品名称：Quasi-Resonant PWM Controller　准谐振PWM控制器

产品型号：SP6878

产品描述：

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).
