TEA19162CT/1J

Overview

The TEA19162CT/1J is a Power Factor Control (PFC) controller IC from NXP Semiconductors, designed for high-efficiency resonant power supplies. It operates as part of a combined solution with the TEA19161T LLC controller and TEA1995T SR controller to deliver 90 W to 500 W output power. The device features an integrated high-voltage start-up source and level shifter, enabling fast startup in under 500 ms at 100 V AC mains. It supports switching frequencies up to 500 kHz while maintaining operation outside the audible range. The controller includes soft-start functionality and a Powergood signal, facilitating compliance with Energy Star and DoE efficiency regulations.

Feature Summary

• Integrated high-voltage start-up source and level shifter for simplified design
• Fast startup capability with continuous SUPIC voltage regulation during initial phase
• Digital control interface for communication with LLC controller and rapid latch reset
• Operation maintained entirely outside the audible frequency range across all modes

Applications

• Desktop and All-in-One computer power supplies
• Liquid Crystal Television (LCD TV) adapters
• Laptop adapters and chargers
• Printer power systems
• Gaming console power units

Procurement Notes

Verify the ordering suffix '1J' corresponds to the SO8 Reel pack packaging configuration when sourcing components. Confirm that the specific revision matches the required datasheet version for integration into designs targeting strict energy efficiency standards. Ensure compatibility with the associated TEA19161T and TEA1995T controllers for the complete resonant topology implementation.

Selection Notes

Select this component for applications requiring a compact, highly efficient PFC stage within a resonant power supply architecture. It is suitable for designs aiming to minimize external component count while meeting global energy regulations. Consider its digital interface requirements when pairing with the primary LLC controller for coordinated mode transitions and protection signaling.

Part Context

This PFC controller belongs to the NXP GreenChip family, optimized for mobile computing and consumer electronics power supplies. It complements the TEA19161T LLC controller and TEA1995T synchronous rectification controller to form a complete, cost-effective resonant power supply solution. This combination allows designers to achieve high efficiency across the entire load range without auxiliary low-power supplies.
