Mechanical dimensions

Note:

Unit: mm [inch]

Pin diameter tolerances: ±0.10mm [±0.004inch]

General tolerances: ±0.5mm [±0.020inch]

Note:

1. Recommend to use module with more than 5% load, if not, the ripple of the product may exceeds the specification, but does not affect the reliability of the product;

2. The recommended unbalance degree of the dual output module load is ≤±5%; if the degree exceeds ±5%, than the product performance cannot be guaranteed to comply

with all parameters in the datasheet. Please contact our technicians directly for specific information;

3. The maximum capacitive load offered were tested at input voltage range and full load;

4. Unless otherwise specified, parameters in this datasheet were measured under the conditions of Ta=25°C, humidity<75%RH with nominal input voltage and rated output

load;

5. All index testing methods in this datasheet are based on Company’s corporate standards;

6. We can provide product customization service, please contact our technicians directly for specific information;

7. Specifications are subject to change without prior notice.

8. It is not allowed to connect modules output in parallel to enlarge the power

Application circuit

Application Notes

1. The wire between the converter and IGBT driver must as short as possible.

2. External filter capacitors should be connected as close as possible to the IGBT

driver.

3. To ensure the high peak gate current, the filter capacitors should be electrolytic

capacitor and ceramic capacitor collocation.

4. The output average power of the IGBT driver should be less than the output

power of DC-DC module.
