Description
Applications
With the features of transformerless and small
footprint, MBI6001 constant current driver is
specifically designed for LED lighting.
The MBI6001 can be directly powered by 110
VAC and provide 18 mA constant current to the
LEDs.

MBI6001-V1.0i
Transformerless AC/DC Constant Current Driver
Line Regulation
IOUT will vary obviously with AC Input voltage. For instance, at VOUT = 50 V, IOUT will increase
20% while input voltage varies from 110 VAC to 100 VAC, but decrease 15% while input
voltage varies from 110 VAC to 120 VAC. For input voltage is usually staying at lower than
100VAC, it is recommended to lower down the VOUT in the application. Otherwise, IOUT will rise
up very quickly and the surface temperature of package will be getting higher than 90°C.
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 110V 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.
