Overview
The TEA1552T/N1,518 is an offline flyback converter IC from the GreenChip II series by NXP USA Inc. It operates in a 14-SOIC package with a switching frequency range of 25 kHz to 125 kHz and supports up to 250 W power output. The device features a 650 V breakdown voltage, an 11 V startup voltage, and a supply voltage range of 8.7 V to 20 V. It functions within a temperature range of -20°C to 145°C TJ and includes protections for current limiting, over-power, over-temperature, and short circuits.
Feature Summary
- Integrates advanced green functions for high efficiency across varying load conditions
- Includes comprehensive fault protection mechanisms for system reliability
- Designed for cost-effective offline flyback topology applications
Applications
- Offline AC/DC power supplies
- Flyback converter designs
- General purpose power management systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance and REACH status prior to integration. Check for obsolete status indicators as availability may be limited. Ensure proper handling for moisture sensitivity level 3 components during storage and assembly processes.
Selection Notes
Select this component for designs requiring a standalone flyback controller without internal switches. Consider the 14-SOIC footprint for PCB layout constraints. Evaluate the 250 W power capability against specific application requirements. Verify thermal management strategies given the 145°C junction temperature limit.
Part Context
Part of the GreenChip II family, focusing on energy-efficient power conversion. Designed to meet stringent energy saving standards such as EuP and Energy Star. Offers a balance between performance and external component count for simplified design workflows.
Replacement Considerations
Check for active equivalents within the TEA1552 series or newer GreenChip generations. Verify pin compatibility and electrical specifications before substitution.
