PMP4371, 380V/350mA Dimmable LED Driver using Single String LLC Solution without Dimming FET
Progetto di riferimento di: Texas Instruments
PMP4371, 380V/350mA Dimmable LED Driver using Single String LLC Solution without Dimming FET. PMP4371 reference design is based on PMP4350 and supports higher output voltage up to 380V. Different from PMP4350, the high voltage LED switch MOSFET is removed and reduced overall cost. With additional resistor and capacitor from LEDSW to CS pin, the LED driver demos good linearity dimming performance under analog and PWM dimming mode. High efficiency (>94%), high PF(>0.94) isolated AC/DC single string output LED lighting solution for high watt (>100W) general LED lighting. The topology uses Transition Mode PFC plus LLC control and achieves high efficiency (>94%) and high PF(>0.94)
