My customer is using TPS56339 to power a RF module like product. They found increasing the boot resistor between BOOT to bootstrap capacitor will improve the RF recevier sensitive.
so far, they increase this res to 100Ω， the RF rev sensitive improve 7dbm(from -83 to -90). I can't tell why this change can get this result. please suggest how big value this resistor can be used? and how doest this resistor
associate with device EMI peformance? thanks.
