LD7820 Primary-Side PWM Controller

The LD7820 is a primary-side feedback controller in CV/CC operation for LED lighting applications. It minimizes the components counts and is available in tiny packages. Those make it an ideal design for low cost applications. The LD7820 provides constant voltage, constant current (CV/CC) operation r.
