TEA1532CT/N1,118

Overview

The TEA1532CT/N1,118 is an offline AC/DC converter manufactured by NXP USA Inc. It belongs to the GreenChip™ II series of SMPS control ICs designed for high efficiency and low standby power in AC-DC power applications. The device utilizes a current-mode control architecture with a maximum switching frequency of 75 kHz. It is implemented using BCDMOS technology and is housed in a PDSO8 package. The component is classified as a voltage converter within the PMIC category.

Feature Summary

• Integrates a complete flyback controller solution for offline AC/DC conversion
• Optimized for high efficiency and reduced standby power consumption
• Employs current-mode control for stable regulation

Applications

• Offline AC/DC power supplies
• Adapters and chargers
• General-purpose switched-mode power supplies

Procurement Notes

Verify the exact suffix against official documentation, as 'CT' may denote specific tape-and-reel or temperature variants distinct from standard 'T' or 'BT' designations. Confirm RoHS compliance status and lead times directly with NXP or authorized distributors, as availability varies by region. Ensure the ordering part number matches the required package and reel specifications for manufacturing integration.

Selection Notes

Select this component for designs requiring a highly integrated, cost-effective flyback controller with low no-load power consumption. It is suitable for applications where space constraints favor an 8-pin SO package. Evaluate thermal performance and input voltage ranges against specific system requirements to ensure compatibility with the internal startup circuitry and protection features.

Part Context

This part is part of NXP's GreenChip™ II family, which focuses on energy-efficient power management. It serves as a core controller for offline converters, replacing discrete solutions with a single IC that integrates oscillator, PWM logic, and protection circuits. The family is widely used in consumer electronics and industrial power adapters.

Replacement Considerations

Consult official substitution guides for equivalents such as the TEA1532T or TEA1532BT. Verify pinout compatibility and electrical parameter alignment before replacement. Cross-reference datasheets to confirm functional equivalence in terms of switching frequency and control topology.
