TEA1530AP/N2,112

AC DC Converters, Offline Switchers Overview

The TEA1530AP/N2,112 is a GreenChip II SMPS control IC from NXP Semiconductors. It supports universal mains supply operation ranging from 70 VAC to 276 VAC and utilizes a fixed frequency converter design suitable for low voltage, high current applications. The device incorporates a proprietary high voltage BCD800 process enabling direct start-up from rectified universal mains voltage. At low power levels, it operates in cycle skipping mode to minimize switching losses, achieving input power below 300 mW at no-load for typical adapters. Protection features include overtemperature protection (OTP), undervoltage protection with foldback during overload, and adjustable overcurrent protection (OCP).

AC DC Converters, Offline Switchers Feature Summary

• High level of integration resulting in very low external component count.
• Cycle skipping mode at very low loads to minimize switching losses.
• On-chip start-up current source for direct mains connection.
• Safe restart mode and latched protection for system fault conditions.

AC DC Converters, Offline Switchers Applications

• Low voltage, high current fixed frequency converter designs.
• Typical adapter applications requiring low standby power consumption.
• Cost-effective power supply designs with minimal external components.

AC DC Converters, Offline Switchers Procurement Notes

Verify the complete part number including the suffix /N2,112 when sourcing, as this indicates specific packaging or tape-and-reel configuration details defined by NXP. Confirm that the TEA1530AP variant matches your requirement for general-purpose input capabilities for latched or safe restart protection, such as OverVoltage Protection (OVP) or output short circuit protection. Ensure compatibility with the required operating temperature range and package type before finalizing procurement.

AC DC Converters, Offline Switchers Selection Notes

Select the TEA1530AP when designing for low voltage, high current applications requiring fixed frequency operation. This variant includes a general-purpose input pin for configuring latched or safe restart protection functions, distinguishing it from standard versions. It is suitable for designs prioritizing low standby power through cycle skipping mode. Consider the integrated high voltage BCD800 process benefits for simplified start-up circuits directly from rectified mains voltage.

AC DC Converters, Offline Switchers Part Context

The TEA1530AP belongs to the GreenChip II family of SMPS controller ICs. This generation focuses on high integration and efficiency improvements over previous models. The 'AP' suffix typically denotes specific pinout or feature variations within the TEA1530 series, often involving additional control inputs for enhanced protection schemes compared to base models like the TEA1530.

AC DC Converters, Offline Switchers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify if other GreenChip II variants meet specific protection requirements without the general-purpose input found in the AP version.
