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.
