B0505KLD-1W Datasheet, PDF (3/3 Pages) MORNSUN Science& Technology Ltd. – SINGLE OUTPUT DC-DC CONVERTER

DESIGN CONSIDERATIONS
1) Requirement on output load
To ensure this module can operate efficiently and reliably, During operation, the minimum output load is not less than 5% of the full 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.
2) Overload Protection
Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is to add a
circuit breaker to the circuit.
3) Recommended Circuit
If you want to further decrease the input/output ripple, a capacitor filtering network may be connected to the input and output ends of the DC/DC
converter, see (Figure 2).
It should also be noted that the capacitance of filter capacitor must be proper. If the capacitance is too big, a startup problem might arise. For
every channel of output, provided the safe and reliable operation is ensured, the recommended capacitance of its filter capacitor sees (Figure 2).

It’s not recommended to connect any external capacitor in the application field with less than 0.5 watt output.
4)The input and the output of the product are recommended to be connected to ceramic capacitor or electrolytic capacitor.
Using tantalum capacitor may cause risk of failure
5) Cannot use in parallel and hot swap
Note:
1. Operation under minimum load will not damage the converter; However, they may not meet all specification listed.
2. Max. Capacitive Load tested at input voltage range and full load.
3. All date in the datasheet are measured according to nominal input voltage, rated output load, TA=25℃, humidity<75%, unless otherwise specified.
4. In this datasheet, all the test methods of indications are based on our corporate standards.
5. The performance in the datasheet is just fit for the part number in the selection guide, and may be different from the customer-designed product,
you can get more details from MORNSUN FAE.
