8.4.2 Standby Mode

Standby mode is a low-power operating mode to help achieve low standby power for the entire power supply. UCC24624 detects the average operation frequency of channel 1 SR MOSFET and enters or exits the standby mode operation automatically. VDD current reduces to IVDDSTBY level. During standby mode, the majority of the SR control functions are disabled, except the switching frequency monitoring and the active pull down on the gate drivers.
