Wide VIN and VOUT 750kHz LLC controller

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.

The automatic capacitive region avoidance scheme along with the adaptive soft start

with reverse recovery avoidance scheme ensures that the device can never work in a

mode where there is a potential to damage the FET’s. This scheme makes the

controller ideal for working with a pre-biased load.

The UCC25660x

family comes with robust protection to help you

design a reliable power supply. The UCC25660x

family has

options supporting high-voltage startup, X-capacitor (X-cap) discharge, OVP

response, and extended Gain range. See details in the device comparison table.
