Frequently Asked Questions
What control method does the UCC2813DTR-5G4 use?
The UCC2813DTR-5G4 uses current-mode pulse width modulation (PWM) control. In this approach, the peak inductor or transformer current is sensed each switching cycle and compared against the error amplifier output to set the duty cycle. Current-mode control offers faster transient response, simpler loop compensation, and inherent cycle-by-cycle current limiting compared to voltage-mode control.
What is the input voltage range for the UCC2813DTR-5G4?
The UCC2813DTR-5G4 operates over an input voltage range of 4V minimum to 12V maximum, with a nominal input voltage of 10V. This range is well-suited to 5V and 12V system power buses commonly found in computing motherboards, industrial control systems, and telecommunications equipment power supplies.
What does the T/R suffix mean in UCC2813DTR-5G4 and what package is it?
The T/R suffix denotes tape-and-reel packaging, suitable for automated pick-and-place PCB assembly in high-volume production. The UCC2813DTR-5G4 is housed in an 8-pin SOIC (R-PDSO-G8) package, a standard small-outline surface-mount form factor widely used in power management ICs for compact, low-profile PCB designs.
Is the UCC2813DTR-5G4 RoHS compliant?
Yes, the UCC2813DTR-5G4 carries a JESD-609 code of e4, confirming it is a lead-free and RoHS-compliant component. This makes it suitable for use in products sold in markets with restrictions on hazardous substances, including the European Union under the RoHS Directive and similar regulations in other regions.
