Application Information Output Current - IOUT
With a selected resistor, R1, being connected between DA and OUT- (refer to Typical Application Circuit), a constant output current, IOUT, can be produced. However, IOUT will vary with VOUT. While VOUT is changed due to different numbers of LEDs being used, IOUT will vary within the range of 15%. Please see Fig. 1.

Surface Temperature vs. VOUT
The temperature on the surface of package will be around 70 C when VOUT is larger than 75V. Temperature will rise up while VOUT is getting smaller. Please see Fig. 2.

Line Regulation
IOUT will vary obviously with AC Input voltage. For instance, at VOUT = 125 V, IOUT 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.
LED Selection Consideration
MBI6001N2N provides constant average output current to drive LEDs. The output to LEDs is actually a sequence of current pulses. Their peak value can be adjusted by a resistor, R2, which connects from PC to REF (refer to Typical Application Circuit). It is recommended to select LEDs with higher peak forward current IF(peak).
Cautions
MBI6001N2N is directly powered by 220V AC. There are several pins with high AC voltage. Please don't touch any pin by hand after the power is on. Also, it is important to keep preventing pins from short circuit.
