Frequently Asked Questions
What control mode does the UCC3813DTR-5 use?
The UCC3813DTR-5 uses current-mode pulse width modulation (PWM) control, which provides cycle-by-cycle current limiting, inherent feed-forward control, and improved transient response compared to voltage-mode PWM controllers.
What is the input voltage range for the UCC3813DTR-5?
The UCC3813DTR-5 operates over an input voltage range of 4V minimum to 11V maximum, with a nominal input of 10V. This wide range makes it adaptable to various auxiliary supply rail voltages in switching power supply designs.
What package does the UCC3813DTR-5 come in?
The UCC3813DTR-5 is available in an 8-pin SOIC (Small Outline Integrated Circuit) package, JESD-30 code R-PDSO-G8. This standard surface-mount package is compatible with automated PCB assembly and available on tape and reel.
What types of power supply topologies is the UCC3813DTR-5 suitable for?
The UCC3813DTR-5 is well-suited for flyback, forward, and other isolated or non-isolated switching converter topologies. Its current-mode control and low-power BiCMOS design make it particularly effective in medium-power offline SMPS and DC-DC converters.
