Overview
The UCC2817APWR is a BiCMOS Power Factor Preregulator IC from Texas Instruments, designed for average current mode control in boost pre-regulators. It operates within a switching frequency range of 6 kHz to 220 kHz and supports global universal line operation. The device features a 16-TSSOP package with a width of 4.40 mm. Electrical specifications include a supply voltage range of 12 V to 17 V, an operating temperature range of -40°C to 85°C, and a startup current of 150 µA.
Feature Summary
- Implements average current mode control to achieve near-unity power factor in boost pre-regulators.
- Provides precise power limiting and overvoltage protection capabilities.
- Features enhanced noise immunity and improved feedforward line regulation.
Applications
- Universal AC-DC power supplies
- Computer peripheral power adapters
- Telecommunications equipment power systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'PWR' corresponds to the TSSOP-16 surface mount package variant. Check for End-of-Life (EOL) status notifications, as related DIP variants have been discontinued. Ensure compliance with RoHS3 standards during procurement validation.
Selection Notes
Select this component for applications requiring average current mode PFC control with high noise immunity. Consider the 16-TSSOP package for surface-mount assembly constraints. Evaluate the 6 kHz to 220 kHz frequency range against system EMI requirements. Verify that the 12 V to 17 V supply range aligns with the controller's auxiliary power needs.
Part Context
This part belongs to the UCCx81xA series of BiCMOS Power Factor Preregulators by Texas Instruments. It is functionally related to other variants such as the UCC2817AN (DIP package) and UCC2819A series. The UCC2817APWR specifically addresses the need for compact surface-mount solutions in high-performance power factor correction designs.
Replacement Considerations
Public confirmed substitute: UCC28180DR. Verify pinout compatibility and thermal performance when transitioning from the UCC2817APWR to alternative controllers.
