TEA19162T/1J

Overview

The TEA19162T/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 control system with the TEA19161T LLC controller and TEA1995T SR controller. The device supports half-bridge switching frequencies up to 500 kHz and features an integrated high-voltage start-up source and level shifter. It ensures operation outside the audio frequency range across all modes and includes soft-start and Powergood functions. The component enables systems to meet 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 V SUPIC regulation during initial phase
• Digital control interface for communication with LLC controllers and fast latch reset
• Operates at switching frequencies entirely outside the audible range

Applications

• Desktop and All-in-One PC power supplies
• LCD Television power units
• Laptop adapters
• Printer power supplies
• Gaming console power supplies

Procurement Notes

Verify the specific ordering suffix /1J corresponds to the SO8 package with reel pack configuration when sourcing. Confirm that the TEA19162T is intended for use in conjunction with the TEA19161T and TEA1995T controllers to form a complete resonant power supply solution. Ensure compatibility with the required digital control interface for proper system integration and protection signaling.

Selection Notes

Select this component for designs requiring a dedicated PFC controller that communicates digitally with an LLC primary-side controller. It is suitable for applications needing high efficiency across varying load conditions while maintaining low no-load input power. Consider the integrated high-voltage features if minimizing external component count is a priority for the power factor correction stage.

Part Context

The TEA19162T belongs to the NXP GreenChip series of AC-DC controllers. It is specifically engineered to work in tandem with the TEA19161T and TEA1995T to create cost-effective, highly efficient resonant power supplies ranging from 90 W to 500 W. This combination allows for the omission of auxiliary low-power supplies due to its superior efficiency profile.
