LD7838H Datasheet (Leadtrend) - High Power Factor Flyback LED Controller

LD7838H, High Power Factor Flyback LED Controller

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 completed protections required.

It minimizes the components counts in either SOP-7 package.

Those make it easy to design with for cost-effect
