Description

General part information

UCC25660 Series

The UCC25660x family is a high-frequency LLC controller implementing Input-Power Proportional Control (IPPC) scheme, along with an enhanced light-load management and multiple protection features.

IPPC widens the control range of the LLC converter simplifies the design of wide input and output-voltage range applications such as LED drivers, battery chargers. It can even work without a PFC for non-universal input applications.

The UCC25660x family’s enhanced light-load management improves while minimizing audible noise. To minimize standby power, the UCC25660x family can directly disable the PFC controller when operating in burst mode.
