UC2825A is a general purpose current mode (voltage mode also) PWM controller for full bridge use.  It’s maximum duty cycle from spec is 85%.  

 Does anyone know a similar full bridge PWM controller with maximum duty cycle >95%?

 Thank you in advance.

    Hello Sam,

    Here is a link to Full-Bridge, PWM, Current-Mode Controllers that support >95% duty cycle.

    I would recommend looking at UC28025 or UCC28251 to focus your search.
