mbi6001-v1.0i transformerless ac/dc constant current driver - 4 - applications information output current - i out with a selected resistor r1 being connected between da and out- (referred to typical application circuit), a constant output current i out can be produced. however, i out will vary with v out . while v out is changed due to different number of leds being used and less than 60v, i out will vary within the range of 15%.

mbi6001-v1.0i transformerless ac/dc constant current driver - 5 - line regulation i out will vary obviously with ac input voltage. for instance, at v out = 125 v, i out will increase 20% while input voltage varies from 220 vac to 200 vac, but decrease 15% while input voltage varies from 220 vac to 240 vac. leds selection consideration mbi6001 provides constant average output current to drive leds. the output to leds is actually a train of current pulses. their peak value can be adjusted by a resistor r2 which connects from pc to v- (referred to typical application circuit). it is recommended to select leds with higher peak forward current i f (peak). cautions mbi6001 is directly power supplied by 220v ac. there are several pins with high ac voltage. please don t touch any pin by hand(s) after voltage in. also, it is important to keep preventing pins from short-circuit.
