The OPA731RD is a versatile device for a variety of applications, and its applications and working principles can help customers better understand its functions and performance in the field of LED lighting – COBs, Engines, Modules.

OPA731RD is a PFC Boost Control IC chip that integrates Buck and PSR controllers, which has high input power factor, low output ripple and excellent EMI performance. This PFC chip is widely used in LED drive circuits, especially in the field of LED lighting – COBs, Engines, Modules.

The main application fields of OPA731RD are LED lighting typically operating between 85VAC to 265VAC. OPA731RD has excellent performance parameters when it comes to LED Driver applications which make it a popular choice in the LED industry.

The main working principle of the OPA731RD is using two stages of switching power supplies to obtain a constant output voltage. In the first stage, the power factor correction circuit converts AC mains power into DC power. In the second stage, the buck converter step-down circuit builds up the output with a constant current or constant voltage source, depending on the requirements.

OPA731RD has many advantages for LED lighting – COBs, Engines, Modules applications. It offers a very high power factor and low THD performance with a wide operating temperature range from -40°C to 130°C. It also provides excellent EMI performance, which satisfies the harsh electromagnetic interference requirements in the market and ensures a stable output feedback control system.

In addition, OPA731RD performs an intelligent output voltage tracking function which is great for LED lighting, allowing the output voltage of the PFC booster to track the current changes so that the excellent power factor and low harmonics of the drive circuit can be maintained.

Those are the main application fields and working principles of the OPA731RD and its great performance when it comes to LED lighting – COBs, Engines, Modules. This versatile PFC chip offers excellent performance and is widely used in many LED applications around the world.
