Overview
The UCC28512N is a Power Factor Correction (PFC) and Pulse Width Modulation (PWM) combination controller manufactured by Texas Instruments. It operates in average current mode with a switching frequency of 200kHz. The device supports a supply voltage range of 9.7V to 18V and features specific UVLO thresholds for VCC and PWM sections. It is housed in a 20-pin PDIP package designed for through-hole mounting, suitable for high-performance power conversion applications requiring integrated control.
Feature Summary
- Integrates PFC and PWM controllers into a single device for simplified design
- Operates in average current mode for improved power factor correction
- Features dedicated UVLO thresholds for VCC and PWM sections
- Supports continuous conduction mode (CCM) operation
Applications
- High-efficiency power supplies
- Server and workstation power systems
- Telecommunications equipment
- Industrial power converters
Procurement Notes
Verify component status as the UCC28512N may be discontinued or obsolete depending on the source date. Confirm package type is 20-PDIP and switching frequency is 200kHz. Check RoHS compliance status. Ensure compatibility with existing PCB footprints. Validate supply voltage range requirements against system design.
Selection Notes
Select this component for designs requiring integrated PFC and PWM control in average current mode. Consider the 200kHz switching frequency and 20-pin DIP package constraints. Verify operating temperature range suitability for the application environment. Evaluate supply voltage requirements against the 9.7V to 18V specification.
Part Context
The UCC28512N belongs to Texas Instruments' family of advanced PFC/PWM combination controllers. It is part of the UCC285xx series, designed for high-performance power factor correction applications. The device integrates essential control functions to reduce component count and simplify board layout compared to discrete solutions.
Replacement Considerations
Check for direct pin-to-pin replacements within the UCC285xx series. Verify functional equivalence regarding switching frequency and control mode. Confirm package compatibility if substituting with other 20-DIP variants.
