【文字介紹】

The LD7830 is a HV start-up Flyback PFC controller special


design for LED lighting. This IC operating on transition(TM)


mode and integrated with completed safety requirement


protections. It minimizes the components counts in a SOP-7


or DIP-8 package. Those make it easy design for costeffective


applications.


With HV start-up technology, high power factor and TM


control, the start-up time and resistor loss could be greatly


reduced. The circuit can easily achieve PF>0.90 which meet


most of the internal standard requirements.


With completed protection functions built inside this IC.


Such as over voltage protection (OVP), over current


protection (OCP), Over load protection (OLP), over


temperature protection (OTP), and short circuit protection


(SCP). It makes circuit easily meet most safety


requirements in both normal and abnormal test.
