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 circuit, please ensure an 220µF

electrolytic capacitors in parallel with the input, which used to

suppress the surge voltage come from the input 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

Trim application & trim resistance

Application circuit for TRIM (Part in broken line is the interior of models)

Note: RT is Trim resistance, a is a self-deﬁned parameter, with no real

meaning. Vo’ for the actual needs of the up or down regulated voltage.

When the Trim function with down regulated is used, If the RT resistor is too low

or “Trim” is short with “+Vo”, the output voltage Vo’ would be lower than 0.9Vo,

which may cause the product to be irreversibly damaged.

It is not allowed to connect modules output in parallel to enlarge the power.
