Overview
The UCC2819APW is a BiCMOS power factor preregulator controller designed for active power factor correction. It operates in continuous conduction mode with a fixed switching frequency of 250 kHz. The device is housed in a 16-pin TSSOP package and supports surface-mount installation. It functions within a temperature range of -40°C to +85°C and draws a typical supply current of 150 µA. This component integrates essential control loops for high-performance AC-DC conversion systems.
Feature Summary
- Implements average current mode control for precise regulation
- Provides near unity power factor correction capabilities
- Integrates complete control functions for preregulator applications
Applications
- Active power factor corrected preregulators
- High-power AC-DC conversion systems
- BiCMOS power factor correction circuits
Procurement Notes
Verify the specific suffix 'PW' confirms the tube packaging format, distinct from the 'PWR' reel variant. Confirm RoHS compliance status via the official datasheet before integration. Ensure design compatibility with the 16-TSSOP footprint and thermal requirements for the specified operating temperature range.
Selection Notes
Select this component when average current mode control is required for high-efficiency PFC designs. The 250 kHz frequency offers a balance between size and efficiency. Consider the TSSOP-16 package constraints for PCB layout. Verify that the 150 µA quiescent current meets system standby requirements.
Part Context
This part belongs to the UCC2819A series of power factor correction controllers. It utilizes BiCMOS technology to achieve high precision and robust performance. The device serves as a core controller for AC-DC power supplies requiring strict power factor standards.
Replacement Considerations
The UCC2819APWR is the reel-packaged equivalent of this tube-part. Cross-referencing with the UCC3819A series may be necessary for functional compatibility, though pinouts and specifications should be verified against official documentation.
