LED Driver IC for Lighting MB39C605 Low-Current, Low-Price LED can be used, reducing the flicker with stable brightness MB39C605 is a PSR-type LED driver IC for LED lighting. Using the information of the primary peak current and the transformer-energy-zero time, it is able to deliver a well regulated current to the secondary side without using an opto-coupler in an isolated flyback topology. Using critical conduction mode, it is able to allow the use of a small transformer. MB39C605 has a built-in phase dimming circuit and is allowed to configure TRIAC dimmable lightings. MB39C605 is able to make output voltage higher (more than 70V) at non-isolation configuration allowing customers to use low current and low price LEDs to reduce the cost of whole of LED lighting. MB39C605 maintains stable brightness even at high voltage output setting and reduces flicker noise. application (example) – high voltage output and non-isolation, 5w e17 led bulb mb39c605-evbsk-01 feature 1: cost reduction with use of low current By making LED driving voltage higher (VLED>70V) at non-isolation configuration, high efficiency and low cost on LED lighting due to use of low current, low price LEDs can be achieved.
