5 Description, Continued

With the built-in standby mode detection based on average switching frequency, UCC24624 enters the standby mode automatically without using external components. The low standby mode current of 180µA supports meeting modern no-load power consumption requirements such as CoC, and DoE regulations. UCC24624 can be used with the UCC25630x LLC and UCC28056 PFC controllers to achieve high efficiency while maintaining excellent light load and no-load performances. Other PFC controllers, such as UCC28064A, UCC28180, and UCC28070 can be used to achieve higher power levels. 1.5-A peak source and 4-A peak sink driving capability allows UCC24624 to support LLC converters up to 1 kW.
