Under the trend of energy saving, environmental protection and the rapid growth of global LED lighting, LED bulbs have become almost household names, and with the advancement of related technologies, LED cost and performance standards have been greatly improved. Yinlianbao Technology focuses on the use of expertise and technology in power management Solutions to provide a complete solution for LED lighting applications, and leverages the experience and expertise in industrial applications to continuously develop new LED driver solutions to meet different application needs. To help the development and progress of the LED lighting market.

For single-segment design applications such as downlights, LED bulbs, spotlights, desk lamps, LED lighting, and intelligent lighting that require high power factor and low harmonic distortion of up to 60W, UnionPay Technology has introduced the SFL950 LED driver solution. The isolated Flyback architecture optimizes high PF values, low THD, high precision LED constant current controllers for LED lighting applications. The chip uses the patented "super-PFC/PSR" and "min-THD control architecture" to achieve conversion efficiencies of up to 90%, power factor above 0.92, THD of less than 10%, and constant current of ±4% for mass production. Precision.

The SFL950 has a patented high-precision closed-loop constant current algorithm that supports quasi-resonant (QR) and DCM modes. It also has built-in load adjustment compensation and AC line voltage compensation, which greatly improves the LED output constant current accuracy. The highest operating frequency of the chip is clamped at 90KHz, and the output GATE soft drive is used to make the LED power supply have better conduction and radiated EMI performance.

The SFL950 uses quasi-resonant (QR) control, which reduces switching losses through valley conduction, significantly increasing energy conversion efficiency. The SFL950 has a very wide VDD operating voltage range, making LED system design more convenient.
