The E_T-1W & F_T-1W series are specially

designed for applications where a group of polar

power supplies are isolated from the input power

supply in a distributed power supply system on a

circuit board. These products apply to:

1) Where the voltage of the input power supply is

fixed (voltage variation ≤ ±10%);

±15

2) Where isolation is necessary between input

and output (isolation voltage ≤3000VDC);

3) Where the regulation of the output voltage and

the output ripple noise are not demanding.

Such as: purely digital circuits, ordinary low

frequency analog circuits, and IGBT power device

driving circuits.

APPLICATION NOTE

1) Requirement on output load

Dual Ou tput

To ensure this module can operate efficiently and reliably, During operation, the minimum

output load could not be less than 10% of the full load. If the actual output power is very

small, please connect a resistor with proper resistance at the output end in parallel to

increase the load, or use our company’s products with a lower rated output power

(E _T-W2/F_T-W2 Series).

2) Recommended testing circuit

If you want to further decrease the input/output ripple, an “LC” filtering network may be

connected to the input and output ends of the DC/DC converter, see (Figure 1).

GND

(Figure2)

It should also be noted that the inductance and the frequency of the “LC” filtering network

should be staggered with the DC/DC frequency to avoid mutual interference. However, the

capacitance of the output filter capacitor must be proper. If the capacitance is too big, a

startup problem might arise. For every channel of output, provided the safe and reliable

operation is ensured, the greatest capacitance of its filter capacitor sees (Table 1).

3) Output Voltage Regulation and Over-voltage Protection Circuit

The simplest device for output voltage regulation, over-voltage and over-current

protection is a linear voltage regulator with overheat protection that is connected to the input

or output end in series (Figure2).

4) Overload Protection

It’s not recommended to connect any external

capacitor in the application field with less than 0.5 watt

output.

Under normal operating conditions, the output circuit of these products has no protection

against overload. The simplest method is to connect a self-recovery fuse in series at the

input end or add a circuit breaker to the circuit.

5) No parallel connection or plug and play
