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.

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).
