LD7830
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 this IC, such as over voltage protection (OVP), over current protection (OCP), over load protection (OLP), over temperature protection (OTP), and short circuit protection (SCP), It enable the circuit to meet most safety requirements either in normal and abnormal test.
