8.2.3 Application Curves

The figures below show the typical switching characteristics of the UCC27624 device used in high-voltage boost converter application. In this application, the UCC27624 is driving the IGBT switch that has a gate charge of
110 nC.

Figure 8-3 UCC27624 Used to Drive IGBT in the Boost Converter
Vin = 210 V, Vout = 235 V, Iout = 1.14 A, Fsw = 125 kHz, driver supply voltage = 15 V, gate resistor = 0 Ω
