UCC2817APW

Overview

The UCC2817APW is a BiCMOS power factor preregulator controller designed for average current-mode control. It operates within a switching frequency range of 6 kHz to 220 kHz and supports a supply voltage of 12 V to 17 V. The device features a low start-up current of 150 µA and functions reliably across an operating temperature range of -40°C to 85°C. It is housed in a 16-TSSOP package with a width of 4.4 mm, intended for surface-mount installation.

Feature Summary

• Implements average current-mode control architecture for high-performance power factor correction
• Integrates a wide input voltage range capability suitable for universal AC line applications
• Features low quiescent current consumption to enhance system efficiency during standby or light-load conditions

Applications

• Offline power factor correction preregulators
• DC-to-DC converter front-end stages
• Universal input power supplies

Procurement Notes

Verify the specific suffix 'PW' confirms the 16-TSSOP package variant. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Check for end-of-life notifications or obsolescence notices from Texas Instruments prior to finalizing procurement decisions.

Selection Notes

Select this component when average current-mode PFC control is required in a compact surface-mount form factor. Ensure the design accommodates the specified 6 kHz to 220 kHz frequency range. Verify that the 16-TSSOP footprint matches the PCB layout constraints and thermal requirements of the target application.

Part Context

This part belongs to the UCC281xA series of BiCMOS power factor preregulators from Texas Instruments. It shares functional similarities with other members like the UCC2817AN but differs in packaging. The series is engineered for efficient power factor correction in offline and DC-to-DC conversion systems.

Replacement Considerations

Publicly confirmed substitute: UCC28180DR. Verify pinout compatibility and electrical parameter alignment before substitution.
