This reference design is a 200-W, dimmable, low THD AC/DC LED power supply with a tunable output voltage from 100 to 200 V. It is designed for use in outdoor lighting applications such as street lighting, road lighting, and so on. This design uses a CCM PFC as front end to achieve low THD and high power factor and proposes two-switch flyback architecture as second stage which helps to meet the cost, efficiency , and design simplicity aspects of LED power supply with adjustable output voltage.
