SLUSAD7B April 2011 – July 2016 UCC25710
PRODUCTION DATA.
The UCC25710 is designed to operate from an external bias supply connected to the VCC input. It has an operating voltage range between 11 V and 18 V with an absolute maximum input voltage rating of 18 V.
In most applications, the high voltage input range of the LLC controller is normally set at about 370 V to 410 V with 390-V nominal. This narrow range of DC input voltage is a constraint of the LLC topology. Setting the maximum and minimum switching frequencies limits the regulation range to these input voltages.
