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.

FEATURE 1: COST REDUCTION WITH USE OF LOWCURRENT
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.
