ZHCSHN1A August 2017 – February 2018 UCC24612
Standby mode is a low-power operating mode to help achieve low standby power for the entire power supply. UCC24612 detects the operating frequency of the SR MOSFET and enters or exits standby mode operation automatically. REG current reduces to IVDDSTBY level. During standby mode, the majority of the SR control functions are disabled, except the switching frequency monitoring, REG monitoring and the active pull-down on the gate driver.
