OPA733WD

LED Lighting - COBs, Engines, Modules

OPA733WD is a high-voltage LED driver integrated circuit adopted advanced technology, advanced design technology and package technology. The load is directly connected to the output terminals of the OPA733WD, and the output current is adjusted by the external current setting resistor. OPA733WD is designed to operate with a common current mode. It is suitable for high-power LED applications. It operates with very low power consumption and low thermal performance. Furthermore, the OPA733WD has a wide range of features to make it a perfect choice for lighting applications.

Application Field and Working Principle

OPA733WD is ideal for use in a variety of LED lighting applications. It is suitable for use in COBs (Chip-on-Board), Engines, Modules and so on. OPA733WD can be used to drive different series or parallel LED arrays or multiple LED strings. With its low tolerance to various environmental conditions, the OPA733WD can be used to drive high-power LEDs in outdoor applications. Because its output voltage is fixed and adjustable, OPA733WD is suitable for a wide variety of configurations.

OPA733WD works with a constant current operation mode. The driver can be easily adjusted by a single external resistor setting Rset. By changing the external resistor, you can adjust the output current of the driver to achieve desired brightness adjustments. The adjustable output current ranges between 10mA and 30mA. The OPA733WD also works with PWM dimming. By applying an external PWM signal with a frequency of up to 1 KHz, the OPA733WD can dim the connected LED to any desired level. When used with PWM dimming, the OPA733WD can reach high efficiency up to 95%.

The OPA733WD also works with low-ripple operation. With its patented internal circuitry, the OPA733WD effectively reduces the AC ripple current to ensure smooth operation and high system stability. This feature allows for a wide range of applications and ensures consistent lighting performance in high power LED lighting systems.

In addition, the OPA733WD is loaded with smart protection functions. It comes with an internal over-temperature, over-voltage, under-voltage and over-load protection, making installation and maintenance safe and easy. The OPA733WD also comes with a built-in Open LED Protection, which shuts off the output if one of the LED strings becomes open.

Conclusion

In conclusion, OPA733WD is an ideal choice for LED lighting applications. It comes with adjustable current outputs, PWM dimming, low ripple operation and smart protection features, making it a perfect choice for outdoor and high power LED lighting applications. It offers high stability, high efficiency and ease of maintenance, making it an ideal choice for a wide range of LED lighting applications.
