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-. (Refer to Typical Application Circuit) It is recommended to select LEDs
with higher peak forward current IF(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.
