Overview
The UCC28065DT is a Power Factor Correction (PFC) controller manufactured by Texas Instruments, belonging to the UCC28065 series. It is designed for natural interleaving transition-mode PFC applications. The device operates within an ambient temperature range of -40°C to +125°C and supports a switching frequency of 800 kHz. It is housed in a SOIC-16 surface-mount package and is classified under PMIC - Power Management ICs.
Feature Summary
- Supports natural interleaving transition-mode power factor correction
- Operates at high switching frequencies up to 800 kHz
- Designed for robust performance across extended industrial temperature ranges
Applications
- Natural interleaving transition-mode PFC designs
- High-frequency power factor correction systems
- Industrial power management circuits
Procurement Notes
Verify the specific suffix 'DT' corresponds to the tube packaging variant when ordering. Confirm that the SOIC-16 package dimensions align with your PCB footprint requirements. Ensure the operating environment stays within the specified -40°C to +125°C range to maintain component reliability and performance specifications as defined by the manufacturer.
Selection Notes
Select this component for applications requiring natural interleaving transition-mode control. Consider the SOIC-16 package constraints and the 800 kHz switching capability during thermal design. Verify compatibility with existing system voltage levels and ensure the controller meets the specific power factor correction topology requirements of the target power supply design.
Part Context
This part belongs to the UCC28065 family of PFC controllers from Texas Instruments. It shares functional similarities with other members like the UCC28065DR but differs in packaging configuration. The DT suffix specifically denotes the tube package format, distinguishing it from reel or cut tape variants within the same product line.
Replacement Considerations
The UCC28065DR serves as a functional alternative within the same family, offering identical electrical characteristics but utilizing reel, cut tape, or MouseReel packaging instead of tubes.
