MB39C601
TRIAC Dimmable LED Driver IC for
LED Lighting
MB39C601 is a flyback type switching regulator contorller IC. The LED current is regulated by controlling the switching on-time or
controlling the switching frequency, depending on the LED load.
It is most suitable for the general lighting applications, for example stocks of commercial and residential light bulbs and so on.
Features
High power factor in single conversion
High efficiency at the light load, at Low Power Mode (LPM) Burst Operation in switching frequency control
Frequency setting depend on the FB pin current : 30 kHz to 130 kHz
Control of the current of Primary Winding without the external sense resistor
TRIAC Dimmable LED lighting
Helps to achieve high efficiency and low EMI by detecting transformer zero energy
