be impressed on the Vcont pin in order to control the output voltage. When Vcont voltage=0V the output voltage(residual output voltage)
should be less than 0.5% of the max output voltage (at Input/Output rating).

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,
so choose one without any chattering. When the output is turned off
by ON/OFF control, the residual output voltage should be within 0.5%.
Place the capacitor as close as possible near to the
converter pin side, to lower the lead inductance.

■ Over current protection
■ Output voltage setting/adjusting
The MHV series installed the over current protection
to protect from the over load and load short. When the
product status is in over load or load short mode, the
output voltage will be decreased, and once the problem
has been removed, the voltage will automatically recover.
The output voltage on the MHV series can be set and adjusted
usuing an external voltage or external adjustable resistor.

1)The MHV series uses a metallic case. When mounting
to a double-sided PCB, the wiring for the converter should
be on the soldering side.
3.76V
3V 4V
1V
2V
0V
Also, this converter will generate high voltages so the
creepage distance of pattern should be taken in when
designing.
The above characteristics (Output voltage -VR resistor value characteristic)
graph is an indication of the resistance value R1 and R2. Please check the
output voltage by the adjustable resistor etc. and adjust at the actual using.
Do not impress voltage higher than 4V+5% on the Vcont.
Choose an adjustable resistor appliance with good temperature
characteristics.
2)When mounting to a double-sided PCB, the land of the
parts side of the high voltage output pin should be as
small as possible.
3)The case of MHV series should be connected to the
-Vin and Vout (Com).
When the resistance value is 5.0KΩ(R1=0Ω, R2=5KΩ), the max.voltage
4.0V will impress to Vcon pin. Therefore, the margin of error for
the resistance value will largely affect the max output voltage, so use the
resistance value as 5.0KΩ±5%.
4)The metallic case does not need to be connecting
to ground.
However, when using and ground with the metallic case,
make the impedance lower as possible between the ground.

MHV Series
■ Vref pin (standard voltage output)
■ Recommended soldering conditions
When adjusting the output voltage with an adjustable
resistor, this pin is used. Vref has a standard output
voltage of 4V. In this case, use an external resistor with
a resistance of 5KΩ.
Soldering conditions for each part is as follows:
1)Using a soldering iron 340 to 360℃
2)Using a soldering tub 230 to 260℃
5 sec.
10 sec.
The resistance(the margin of error) of external adjustable
resistor will affect the setting value of Vref pin voltage,
so use a resistor with an accuracy of 5KΩ±5%.
The type of adjustable resistor will not matter, however one
with a well temperature coefficient is recommended.
Vref voltage : 4±0.3V
■ Lowering the output noise even farther
The MHV series does need any external parts, however
to lower the output noise even farther, connect a
capacitor C2 like the figure below.

When lowering the output noise even more, keep in mind the
input/output wiring, creepage and area distance, while
keeping the wiring as thin as possible and layout the C2 near
the Load.
■ Temperature derating
When using the product where the ambient temp. is
higher than 50℃, follow the derating graph below.
The minimum load resistance is set for each series.
When using higher than 50℃, set the load resistance
high by following the below graph.
Point!
1) When choosing a capacitor that connect to the input, choose
one which is a high frequency characteristic capacitor.
2) Common line should be designed thick and short to make same
impeadance small.
3) The capacitor which is connected to the output side should
be able to withstand the pressure, and connect 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.
Start up is possible in this area. However the reliability
is not guaranteed.
