Introduction

The XBDAWT-00-0000-00000HDE6 is a low voltage drive for LED lighting system applications, designed for white LED lighting. It is designed to drive up to six white LED strings that connected in parallel and could be diversified with external resistors, which may be fitted with regulators for brightness control. It features the following features: low power consumption, high current capability and low leakage current, high efficiency, wide input voltage range (from AC 90V to AC 270V) and its current rating is determined by external resistors. In this article, we will discuss the application field and working principle of the XBDAWT-00-0000-00000HDE6.

Application Field

The XBDAWT-00-0000-00000HDE6 can be used in a wide range of application field such as but not limited to commercial, retail, hospitality and residential lighting. It is intended for use in white LED lighting applications to drive up to six white LED strings that connected in parallel and could be diversified with external resistors. The high efficiency of the XBDAWT-00-0000-00000HDE6 and its low-power consumption at operating voltage makes it ideal for energy conscious project. Furthermore, its wide input voltage range from AC 90V to AC 270V makes it suitable for international project irrespective of the main grid voltage.

Working Principle

The XBDAWT-00-0000-00000HDE6 uses a set of internal circuitry to convert AC mains power into a low voltage DC supply. This low voltage DC supply is then used to drive the LED strings in the application. The XBDAWT-00-0000-00000HDE6 uses an inductive-capacitive (LC) circuit to filter out unwanted ripple current. The conversion process is regulated by means of voltage programming and current control loops. The voltage programming loop is used to detect the output voltage and adjust the duty cycle of the pulse-width modulation (PWM) signal to maintain the desired output voltage. The current control loop has two primary control sections. The first section is the analog control circuit that sets the effective current on the string of LEDs. The second section is the PWM circuit, which adjusts the output current of the XBDAWT-00-0000-00000HDE6 by modulating the output voltage.

Conclusion

The XBDAWT-00-0000-00000HDE6 is a highly efficient low voltage drive for LED lighting system applications, designed to drive up to six white LED strings that connected in parallel and could be diversified with external resistors. It features low power consumption, high current capability, wide input voltage range, and high power efficiency. It uses a set of internal circuitry to convert AC mains power into a low voltage DC supply and then uses a inductive-capacitive (LC) circuit to filter out unwanted ripple current. It is suitable for commercial, retail, hospitality, and residential lighting and international project.
