Note 1: The output voltage is controlled by the Vcont voltage being impressed. Connect an external voltage to impress to the

the Vcont pin to control the output voltage. When Vcont voltage =0V, the output voltage (output residual voltage) must be

within 0.5% of the max output voltage (when input/output is rated)

■ Standard usage

■ Over current protection

The BYH series has an over current protection to protect against

over load and load shortage. When over load or load shoratage

occurs, if the output voltage is lowered an activated, and the

reason has been removed, the output will auto recover.

100% output

The BYH series does not need any external parts, however

the longer the power supply and converter distance is, and

thinner the input line is to the input filter, the higher the impedance

will be, and connected a capacitor to CI is recommended.

As long as the capacitor is connected, the design should be

1) The BYH series uses a metallic case. When using a double

mounting PCB, the wiring to the converter should be done on

the soldering surface. Also, this converter will have a high voltage

so make sure to create enough creepage distance.

determined by the output.

The metallic case does not need to be in contact with anything else.

However, if you would like to bring the metallic case into contact, it

should be used to lower the anti ground impedance.

■ Temp derating

■ When lowering the output noise even more

When using the product where the ambient temp is

higher than 50℃, follow the derating graph below.

Increase the load resistor as the temp increases.

The BYH series does need any external parts, however

to lower the output noise even farther, connect a

capacitor C2 like the figure below.

The product may start up in this area, however reliablity is not

insured.

When lowering the output noise eve more, keep in mind the

■ Preventing inverse connections

Points!

The converter may break if the polarities are reversed.

If there is a possibility in which the connections maybe

reversed, connect a diode and fuse like below.

1) When choosing a capacitor, choose one which is a

high frequency characteristic capacitor.

2) Earth (COMMON) line should be bundled and kept small

while the wiring pattern is thick and short.

3) The capacitor which is connected to the output side should

be able to withhold the pressure, and connected to the load side.

At this time, the capacitor lead should be shortened. Also,

when the load response time is a problem, please be aware

of the time constant.

■ About washing the product

This product can not be washed as a whole. However, when

there is a need to wash the product, use an IPA to wash

only the soldered surface with a hand brush.
