LD7830H Description
The LD7830H 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.
