4.8DBTW_3 series
4.8W - Dual Output - Wide Input - Isolated & Regulated regulated
IGBT dedicated DC-DC converter
Typical application
All the IGBT driver of this series are tested according to the recommended circuit (see Fig. 2) before delivery.
If it is required to further reduce input and output ripple, properly increase the input & output of additional capacitors Cin and Cout or
select capacitors of low equivalent impedance provided that the capacitance is no larger than the max. capacitive load of the product.

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.

Mechanical dimensions
Note:
Unit: mm [inch]
Pin diameter tolerances: 0.10mm [ 0.004inch]
General tolerances: 0.5mm [ 0.020inch]
Note:
1. The lead connecting the power supply module and IGBT driver should be as short as possible during use;
2. The output filtering capacitor should be as close as possible to the power supply module and IGBT driver;
3. The peak of the IGBT driver gate drive current is high, so low internal resistance electrolytic capacitor is recommended to be used for
the power supply module output filter capacitor;
4. The average output power of the driver must be lower than that of the power supply module;
5. Consider fixing with glue near the module if being used in vibration occasion;
6. The max. capacitive load should be tested within the input voltage range and under full load conditions;
7. Unless otherwise specified, data in this datasheet should be tested under the conditions of Ta = 25°C, humidity <75% when inputting
nominal voltage and outputting rated load;
8. All index testing methods in this datasheet are based on our Company’s corporate standards;
9. The performance indexes of the product models listed in this manual are as above, but some indexes of non-standard model products
will exceed the above-mentioned requirements, and please directly contact our technicians for specific information;
10. We can provide product customization service;
11. Specifications of this product are subject to changes without prior notice.
12. The product does not support output in parallel with power per liter or hot-swappable use
