Additional information

5.1

Gate driver

The 2ED24427N01F is a high current gate driver for single ended applications. Due to its very high output current and low

thermal resistance vs. pcb, it is capable to drive Mosfets with very large input capacitance at frequencies up to fsw = 200

kHz or higher without the need of negative supply. The following Figure 4 shows the typical application schematic:

Figure 4

Typical gate driver application

Rg values have to be selected based on the requested tr and tf of the application and may vary between 2.5 Ω and 20 Ω,

while the input capacitance of the fets can go up to 20 nF or more depending on the switching frequency. Since the

very high peak output current, the bypass capacitor Cpb has to be mounted in the close proximityof the Vcc and COM

pins and a ceramic type with low ESR has to be chosen.

5.2

Bridge tied gate transformer driver (BT-GTD)

This is a popular configuration that allows driving high side fets using a low side gate driver, the Figure 5 shows the typical

schematic for a single fet drive:

Bridge tied gate driver configuration

In this configuration the gate transformer parameters have a very important role, most manufacturers indicate the

following in their datasheets:
