■ ON/OFF control

By opening and closing the ON/OFF pin and -Vin pin

the external voltage can be turned on and off.

Between the ON/OFF pin (5) and -Vin pin (2)

　　　　1) Open will turn the output ON

　　　　2) Short(0 to 1.0V､1mAmax) will turn the output OFF

The ON/OFF pin is internally pulled up to the +Vin, so be careful

of the voltage from the switching element of the ON/OFF pin

(photo couplers, transistors, etc)

Keep the (5) open when not using the ON/OFF control.

The MHV series does not require any external parts,

however when the impedance is high, for example:

the distance between the power supply and converter

long, the input line is thin, or the input side has a filter

then connecting a capacitor C1 to the input side is

recommended.

The chattering to the ON/OFF pin will affect the output voltage,

Place the capacitor as close as possible near to the

so choose one without any chattering. When the output is turned off

converter pin side, to lower the lead inductance.

by ON/OFF control, the residual output voltage should be within 0.5%.
