1-4. Over current protectionAn over current protection circuit is incorporated in the model, and if over current occurs, the output voltage is lowered. By removing the over current and shorted condi-tions, the output voltage automatically resumes. Note that if the over current status continues for 30 seconds or over, the internal elements of the converter may be deteriorated or damaged. The current value, from which it is judged as an over current, is not to be lower than the nominal current

1-5. Over voltage protectionAn over voltage protection function is not incorporated in the model. Be careful if an external voltage over the nomi-nal voltage is applied, damage may be caused.

1-6. Low input voltage protectionThis series is equipped with the low input voltage protec-tion in order to prevent malfunction due to low input volt-age. The converter stops operation if the input voltage become lower than the set voltage.

Serial connection is applicable by wiring as shown in the figure below (left). If output voltage is not generated by this connection, connect a Schottky barrier diode in which the forward voltage is possibly low.Also note that the Schottky barrier diode should have a reverse voltage that is twice or over the value of the voltage between +Vout and -Vout.And the output current should be the same or lower than the nominal current value, whichever is smaller in the convert-ers.

The above setting value is fixed and cannot be adjusted externally.

2-1. Output ripple noise measurement methodThe measured value of the converter noise may differ de-pending on the measurement method. Measurement should be conducted in a position close to the output terminal. When connecting a prove, do not allow a loop to be config-ured in order not to pick up flux.As well, note that the spike voltage greatly differs depend-ing on the ripple voltmeter and frequency band of the oscil-loscope.Our noise measurement is conducted by the wiring shown in the figure below and in the frequency band of 50MHz.

When the distance to the input of the converter from the input power supply is long, the impedance of the input line can become high, causing high spike noise.In this case, it is recommended to connect a capacitor as close as possible to the input of the DC-DC converter.

2-3. Output ripple & noiseTo reduce Output ripple & noise, connect a capacitor to the output of the converter. In addition, reduction can be enhanced if a π type filter is incorporated as shown in the figure below. In this case, use of a coil with around 100µH is recommended.

To reduce common mode noise, connect a capacitor with around 1000pF between the primary GND and the second-ary GND, as shown in the figure below.In this case, note that if the capacitor that is connected is too large, coupling capacitance between input and output becomes large.Also be careful about the withstand voltage of the capacitor (500V or over is desirable with consideration of the insula-tion withstand voltage).

For products with 10W, capacitors with 1000pF are inter-nally connected between primary and secondary.

2-6. Radiation noiseRadiation noise of the converter can be reduced by con-necting the case terminal to the input or output GND ter-minal. The effectiveness varies depending on the device. Check it on the actual device.Regarding wiring, use GND line and solid pattern for the bottom of the converter as much as possible.- SMD models are not equipped with case terminals.

The reflow must be 1 time only.(Do not reflow with the on-board module on the motherboard underside.)
