9.4.3 Operation Under 100% Duty Cycle Condition

The UCC27710 allows constant on or constant off operation (0% and/or 100% duty cycle) as long as the VDD and VHB bias supplies are maintained above the UVLO thresholds. This is a challenge when boot-strap supplies are used for VHB. However, when a dedicated bias supply is used, constant on or constant off conditions can be supported. Also consider the HI and LI interlock function prevents both outputs from being high.
