APPLICATION NOTES

1. Requirement on output load

To ensure this module can operate efﬁciently and reliably, the minimum output load cannot be less than 10% of the full load during

operation. If the actual output power is small, please connect a resistor at the output end in parallel to increase the load.

2. Recommended circuit

This series has been tested according to the following recommended testing circuit before leaving the factory. This series should be

tested under load (see Figure 3). If you want to further decrease the input/output ripple, you can increase capacitance properly or

choose capacitors with low ESR (see Table 3). However, the capacitance must not exceed the maximum capacitive load or a start-up

problem might arise (see Table 4).

Notes:

1. Minimum load shouldn't be less than 10%, otherwise ripple may increase dramatically. Operation under minimum load will not damage the converter, however, they may

not meet all speciﬁcations listed.

2. Maximum capacitive load is tested at input voltage range and full load.

3. All speciﬁcations are measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise speciﬁed.
