SP5875 高压启动LD7575
The SP5875 is a current-mode PWM controller with excellent power-saving operation. Itfeatures a high- voltage current source to directly supply the startup current from bulk capacitor andfurther to provide a lossless startup circuit. The integrated functions such as the leading-edgeblanking of the current sensing, internal slope compensation, and the small package provide theusers a high efficiency, minimum external component counts, and low cost solution for AC/DCpower applications.

SP5875 offers complete protection functions including cycle-by-cycle current limitingprotection(OCP), over load protection(OLP),VDD over voltage protection(OVP), VDD overvoltage clamp and under voltage lockout(UVLO). Furthermore, the special green-mode controlprovide the solution for users to design a high performance power circuit easily.
