Note:
1. Operation under minimum load will not damage the converter; However, they
may not meet all specification listed, and that will reduce the life of product.
2. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage
and rated output load unless otherwise specified.
3. In this datasheet, all the test methods of indications are based on corporate
standards.

Sense of application and precautions
When not using remote sense
Notes:
1. When not using remote sense, make sure + Vo and Sense + are shor-
ted, and that 0V and Sense- are shorted as well;
2. Keep the tracks between + Vo and Sense +, 0V and Sense- as short
as possible. and close to the terminal. Avoid a looping track. If noise
interferes the loop, the operation of the power module will become
unstable.
When remote sense is used
Notes:
1. Using remote sense with long wires may cause output voltage to be-
come unstable. Consult us if long sensing wiring is necessary.
2. Sense tracks or wires should be as short as possible. If using wires, it
should not use twisted-pair or shielded wires.
3. Please use wide PCB tracks or a thick wires between the power supply
module and the load, the line voltage drop should be kept less than
0.3V. Make sure the power supply module‘s output voltage remains
within the specified range.
4. The impedance of wires may cause the output voltage oscillation or a
greater ripple, please take adequate assessments before using.
Typical application
If not using Gaptec’s recommended cicuit, please ensure an 220µF
electrolytic capacitors in parallel with the input, which used to
suppress the surge voltage come from the iuput terminal.
All the DC/DC converters of this series are tested according to the
recommended circuit (see Fig. 1) before delivery.
If it is required to further reduce input&output ripple, properly
increase the input & output of additional capacitors Cin and Cout
or select capacitors of low equivalent impedance,provided that the
capacitance is no larger than the max. capacitive load of the
product.
