LED Drivers

The PLED200W-081 is a LED driver used for applications requiring greater than 250W output at max efficiency. It is a two-stage driver that can be used for a variety of LED lighting applications, such as outdoor lighting fixtures, linear lighting, and home decoration lighting.

The driver uses a step-down topology to convert the input voltage to the desired output voltage and regulates it at the desired level, thanks to its built-in current and voltage protection. It also features over-current and short-circuit protection to prevent any damage to components due to overloads and shorts.

Working Principle

The PLED200W-081 utilizes a step-down converter topology, where the input voltage is regulated through the use of a high-side switch, while the output voltage is regulated by a low-side switch. The output voltage is determined by the duty cycle of the high-side and low-side switches, and the current is determined by a current-control element. It has a high-power range, which can adjust the voltage within the range of 200V to 400V. The output voltage is controlled by the secondary output voltage, and the output current is limited by the secondary output current.

The driver has an advanced protection design to ensure the safety of the application and the system as a whole. It can provide protection from thermal runaway. In addition, it can differentiate between short-circuits and open-circuits, which can prevent any possible damage due to accidental wiring. Moreover, the driver has a built-in EMC filter to reduce electromagnetic interference and a power-saving feature that can save energy during standby mode.

In addition, the PLED200W-081 has a wide temperature range and an automated temperature control loop. This not only helps to increase the system stability, but also allows for a more efficient operation. Finally, the driver incorporates a slow-start feature that gradually increases the voltage and current to prevent any currents spikes that could damage the components.

Applications

The PLED200W-081 driver is primarily used for applications that require a high output power, such as outdoor or linear lighting fixtures, stage lighting, flood lighting, and landscape lighting. It is also suitable for LED decorative lighting, such as accent lighting for buildings, streets, gardens, and parks.

In addition, this driver can be used for solar street lights, emergency lighting, CFL lamps, LED display panels, fluorescent fixtures, and general illumination applications. Furthermore, it can be used for retail LED lighting, such as grocery stores, hotels, and restaurants.

Conclusion

The PLED200W-081 is an advanced LED driver that can provide up to 250W of output power. It uses a step-down topology to regulate the output voltage and current while providing over-current and short-circuit protection. The driver is suitable for a wide range of applications, including outdoor lighting fixtures, linear lighting, and decorative lighting. It also has advanced features such as a built-in EMC filter, temperature control, and slow-start to ensure that the system is protected and operates at peak efficiency.
