7. PMBus Command Descriptions

POWER_GOOD_ON (5Eh)

Definition: Sets the voltage threshold for Power-good indication. Power-good asserts after the output voltage exceeds

POWER_GOOD_ON and deasserts when the output voltage is less than VOUT_UV_FAULT_LIMIT. Renesas

recommends to set POWER_GOOD_ON higher than VOUT_UV_FAULT_LIMIT.
