TYPICAL CHARACTERISTICS
APPLICATION NOTE
Requirement on output load
To ensure this module can operate efficiently and
Temperature Derating Graph
reliably, During operation, the minimum output load is not
less than 10% of the full load, and that this product
should never be operated under no 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.

Recommended testing circuit
If you want to further decrease the input/output ripple, an

It should also be noted that the inductance and the

However, the capacitance of the output filter capacitor
