MAX20051AUD/V+T Application Field and Working Principle
Introduction: MAX20051AUD/V+T is a low-cost LED driver designed for small to medium LED luminaires and to support the demand for continuous dimming for the energy efficient lighting. This LED driver was designed with a power factor correction (PFC) circuit and high switching frequency (up to 1 MHz).
Category: PMIC - LED Drivers.
Application Field:
The MAX20051AUD/V+T is applicable to low-cost LED lighting, such as: residential, office, industrial and commercial lighting; street lighting; down-lighting; spot lighting; and lighting of aquariums or ponds. Because of its high frequency (up to 1 MHz), and ability to support dimming, the MAX20051AUD/V+T is immensely versatile and can be used in a wide variety of lighting applications.
Working Principle:
The MAX20051AUD/V+T is a PFC driver, meaning it achieves its high power factor by reducing the current harmonic content and utilizing the power factor correction (PFC) circuit. The MAX20051AUD/V+T uses a constant-on-time (COT) control method to regulate the switching frequency and optimize its power factor. COT is an efficient and reliable control method to achieve fast-transient response and less overshoot/undershoot at the output. The switching frequency of the MAX20051AUD/V+T can adjust itself automatically based on the input voltage, offering better performance for different applications and rated voltages.
In addition, the MAX20051AUD/V+T LED driver includes the LED ON/OFF control and dimming control function. This allows the driver to adjust the LED brightness output by the customer’s choice of dimmer, thus saving energy and offering a more selectable range of lighting intensity.
The MAX20051AUD/V+T also incorporates various safety protections, including over-temperature protection (OTP), over-voltage protection (OVP), over-current protection (OCP), open LED positive/negative protection (LPP/LPN), open LED/output short/load circuit protection (LOS/LDS) and active power factor correction (PFC). This ensures that the LED is operated in a safe and reliable condition, and protects both the fixture and its users.
Conclusion:
The MAX20051AUD/V+T is a versatile, efficient and reliable LED driver that is suitable for a variety of lighting applications. It offers efficient power factor correction and high switching frequency with a wide range of dimming control options. Furthermore, the MAX20051AUD/V+T provides comprehensive safety protection features to ensure safe and reliable operation of the luminaire.
