Applications Information

Output Current - I_OUT

With a selected resistor R1 being connected between DA and OUT- (refer to Typical Application

Circuit), a constant output current I_OUTcan be produced.

However, I_OUTwill vary with V_OUT. While V_OUTis changed due to different number of LEDs being

used and less than 60V, I_OUTwill vary within the range of ± 15%. (see Fig. 1)

Fig. 1- I_OUTvs. V_OUT(@ 110 VAC, Ta= 25 °C)

60 V_OUT(V)

Surface Temperature vs. V_OUT

The temperature on the surface of package will be around 60 °C when V_OUTis smaller than 60V.

Temperature will rise up while V_OUTis getting larger. (see Fig. 2)

Transformerless AC/DC Constant Current Driver

Line Regulation

I_OUTwill vary obviously with AC Input voltage. For instance, at V_OUT= 50 V, I_OUTwill 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 V_OUTin the application. Otherwise, I_OUTwill 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 I_F(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.
