The TEA1761T/N2/DG,118 is a highly integrated circuit manufactured by NXP Semiconductors, designed to deliver top-notch performance in switch mode power supplies (SMPS). This GreenChip™ III controller IC is specifically tailored for efficient power conversion and management in a wide array of electronic devices, from TVs and monitors to adapters and power supplies for computers and other consumer electronics.

Featuring a combination of several energy-saving technologies, the TEA1761T/N2/DG,118 stands out with its low standby power consumption, making it an ideal solution for applications that require compliance with energy efficiency regulations such as Energy Star or the European Code of Conduct. It operates in quasi-resonant mode at high power levels for reduced electromagnetic interference (EMI) and switches to a special low-power mode under light-load conditions to maintain high efficiency across a broad load range.

This control IC incorporates a high-voltage startup circuit, which allows for a quick and efficient startup without the need for additional external components. The built-in OverVoltage Protection (OVP), OverCurrent Protection (OCP), and OverTemperature Protection (OTP) features ensure the safety and reliability of the power supply by preventing damage from abnormal operating conditions.

The TEA1761T/N2/DG,118 is also designed with ease of use in mind. Its pin-to-pin compatibility with earlier GreenChip™ products allows for design flexibility and easy upgrades to existing power supply designs. The IC is housed in a compact SO-8 package, making it suitable for space-constrained applications.

Key features of the TEA1761T/N2/DG,118 include:

• High level of integration for a simplified design
• Low standby power consumption for energy savings
• Quasi-resonant operation for reduced EMI
• High-voltage startup circuit for efficient power-up
• Comprehensive protection features for enhanced safety
• Pin compatibility with previous GreenChip™ ICs for design versatility

Whether you're designing a new power supply or upgrading an existing one, the TEA1761T/N2/DG,118 provides a robust, efficient, and cost-effective solution that meets the growing demands for energy efficiency in power electronics.
