9.2.2.1 Selecting HI and LI Low Pass Filter Components (RHI, RLI, CHI, CLI)

It is recommended that users avoid shaping the input signals to the gate driver in an attempt to slow down (or delay) the signal at the driver output. However it is good practice to have a small RC filter added between PWM controller and input pin of UCC27710 to filter the high frequency noise, like RHI/CHI and RLI/CLI which is shown in Figure 44.

Such a filter should use a RHI/RLI in the range of 10 Ω to 100 Ω and a CHI/CLI between 10 pF and 220 pF. In the example, a RHI/RLI = 49.9 Ω and a CHI/CLI = 33 pF are selected.
