LD7830 - High Power Factor Flyback LED Controller

General 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 complete protections required for safety and therefore it’s an excellent solution to minimize the components counts.

Key Features

  • High voltage (600V) startup circuit.
  • High Power Factor Flyback PFC controller.
  • High-efficiency Transition mode operation.
  • Wide UVLO (16Von and 7.5 Voff).
  • VCC OVP (Over Voltage Protection).
  • OLP (Over Load Protection).
  • OCP (Cycle by cycle current limiting) Vcs=0.5V.
  • Internal OTP (Over Temperature Protection).
  • 500/-800mA Driving Capability.
  • Internal OTP function.

LD7830 8/17/2012 High Power Factor Flyback LED Controller with HV Start-up REV: 01a General 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 complete protections required for safety and therefore it’s an excellent solution to minimize the components 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.
