TEA1742T/N1,118

Overview

The TEA1742T/N1,118 is a Power Factor Correction (PFC) controller designed for Continuous Conduction Mode (CCM) applications. Manufactured by NXP USA Inc., this integrated circuit operates within a supply voltage range of 10.6 V to 38 V and features a low startup current of 60 µA. It supports switching frequencies up to 125 kHz and is housed in an 8-SOIC package with a width of 3.90 mm. The device is rated for operation across a wide temperature range from -20°C to 150°C.

Feature Summary

• Supports continuous conduction mode (CCM) power factor correction topologies
• Integrated control logic for high-efficiency AC-DC conversion stages
• Wide operating supply voltage range accommodating various input conditions

Applications

• Power factor correction stages in switch-mode power supplies
• AC-DC converter systems requiring CCM operation
• General-purpose power management ICs for electronic equipment

Procurement Notes

Verify the specific ordering suffix and tape-and-reel specifications against official NXP documentation before procurement. Confirm that the component status aligns with project requirements, as availability may vary. Ensure compatibility with existing PCB footprints and thermal management designs. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when designing PFC circuits that require CCM operation and a wide input voltage range. Consider the 8-SOIC package constraints for board space and thermal dissipation. Evaluate the 125 kHz maximum frequency against electromagnetic interference (EMI) requirements. Verify that the 60 µA startup current meets the system's standby power constraints.

Part Context

This component belongs to the NXP GreenChip family of AC-DC controllers, which are engineered for high efficiency and low power consumption. The TEA1742T specifically targets PFC applications, complementing other controllers in the series such as the TEA173x and TEA175x families. These devices are commonly used in modern power supplies to meet regulatory standards for power quality and energy efficiency.
