High Power Factor Flyback LED Controller with HV Start-up
REV. 00
General Description
The LD7838H is a 700V HV start-up flyback PFC controller, specially designed for LED lighting. This device operates in transition mode(TM) and integrates with pleted protections required. It minimizes the ponents counts in either SOP-7 package. Those make it easy to design with 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 this...
