LP87642Q1EVM: LP87642Q1EVM Switching Frequency Confirmation

Part Number: LP87642Q1EVM

I orderred evaluation board LP87642Q1EVM. According to user guide, default 4-phase single output configuration has switching frequency of 2.2MHz. How do I double check the switching frequency?

Is 4.4MHz freqeuncy support with this default hardware configuration (BUCK1+BUCK2+BUCK3+BUCK4). If yes, can you provide NVM configruation example file?

    You can check the fsw on the any buck output switch node using high frequency probe.

    No by default that EVM has 2.2 MHz configured.
