See Applications Information Application Information Output Current - IOUT IOUT (mA) 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%.

Temperature will rise up while VOUT is getting smaller.

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. -4- February, 2003, V1.2 MBI6001N2N Transformerless AC/DC Constant Current Driver Outline Drawings DIP14 – P – 300 – 2.54 -5- February, 2003, V1.2
