This is a high-performance LED lighting driver circuit with a non-isolated buck single-stage PFC, featuring advantages such as fewer external components, simple design, high power factor, and high constant current accuracy.
The SP5310 is a high-performance, non-isolated, buck-type single-stage PFC LED lighting driver circuit. It features a small number of external components, simple design, high power factor, and high constant current accuracy. Using a quasi-resonant conduction control method, it achieves higher conversion efficiency. In practical applications, it is suitable for non-isolated lighting driver solutions under 20W.
Functions
● Valley voltage turn-on MOSFET to achieve low switching loss
● 0.3V current detection reference voltage, achieving lower sampling resistance and lower conduction loss
● Large MOSFET drive current (0.5A output current, 2A absorption current)
● Low start-up current (typically 20uA)
● Reliable LED short-circuit and open-circuit protection
● Power factor greater than 0.9
Applications
● LED lighting
● Bulb lights
● Fluorescent tubes
● PAR lamps
● Recessed lights
