Isolation speciﬁcations

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 <75ꢀ, nominal input

voltage and rated output load unless otherwise speciﬁed.

3. Only typical models listed, other models may be diﬀerent, please contact our

QS4A_1.5UP series

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

Typical application circuit

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

citor 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 con-

dition of safe and reliable operation, the recommended capacitive load

values are shown in Table 1.

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 the

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

power is not less than 10ꢀ).
