QT8E_3UP Series

0.25W - Single Output DC-DC Converter - Fixed Input - Isolated & Unregulated

DC-DC Converter

0.25 Watt

The QT8E_3UP products are an ideal and economical solution for many applications

where noise reduction, voltage isolation, voltage conversion in distributed power

systems are required. These converters are qualiﬁed for the higher temperatures

requested by lead-free reﬂow solder processes, especially for automated SMD pro-

duction lines.

3000VDC isolation

Industry standard pinout

RoHS Compliance

Short circuit protection (SCP)

Small footprint (over pins

1.37cm²)

Eﬃciency up to 78%

Operating temperature range:

-40°C ~ +105°C

Power density 1.8W/cm3

These products apply to:

1) Where the voltage of the input power supply is ﬁxed

(Voltage variation ≤ 10ꢀ)

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.

Typical application circuit

Fig. 1

Fig. 2

If it is required to further reduce input and output ripple, a ﬁlter capaci-

tor may be connected to the input and output terminals, see Fig. 1.

Moreover, choosing a suitable ﬁlter capacitor is very important, start-up

problems may be caused if the capacitance is too large. Under the

condition of safe and reliable operation, the recommended capacitive

load values are shown in Table 1.

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 (see

Fig. 2).

Output load requirements

In order to ensure the converter can work reliably with high eﬃciency,

the minimum load should not less than 10ꢀ rated load when it is used.

If the needed power is indeed small, please parallel a resistor on t the

output side ( The sum of the eﬃcient power and resistor consumption

power is not less than 10ꢀ).
