This is a high-performance single-stage PFC non-isolated buck LED lighting converter circuit. It integrates a high-voltage MOSFET and features very few external components, simple design, high power factor, and high constant current accuracy.
The SP5318F is a high-performance single-stage PFC non-isolated buck LED lighting converter circuit. It integrates a high-voltage MOSFET and features minimal external components, simple design, high power factor, and high constant current accuracy. It uses a quasi-resonant conduction control method, significantly improving conversion efficiency. In applications, the output power is up to 30W.
Functions
● Integrated high-voltage MOSFET, simplifying external application design
● Low MOSFET on-resistance, reducing conduction losses
● Valley voltage turn-on MOSFET, reducing switching losses
● 0.3V current detection reference voltage, allowing for a smaller CS sampling resistor, thus reducing conduction losses
● 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
● Tubes
● PAR lamps
● Recessed lights
