8/17/2012 High Power Factor Flyback LED Controller with HV Start-up REV: 01a General Description The LD7830 is a HV start-up Flyback PFC controller, specially designed for LED lighting appliances. It operates in transition(TM) mode and integrates with plete protections required for safety and therefore it’s an excellent solution to minimize the ponents counts. Those make it ideal for cost- effective applications. With HV start-up technology, high power factor and TM control, the start-up time and resistor loss could be minimized efficiently. The circuit can easily achieve PF>0.90 to meet most of the international standard requirements. With pleted protection built inside...
