Overview of UCC3813D-1
When it comes to package options, temperature-range options, maximum duty cycle, and critical voltage levels, the UCC3813D-1 offers flexibility to meet specific design requirements. For battery-operated systems, devices with lower reference voltage such as the UCC3813-3 and UCC3813-5 are well-suited, while the UCC3813-2 and UCC3813-4, with higher reference voltage and UVLO hysteresis, are ideal choices for off-line power supplies
Key Features
