TEA1723AT/N1,118

The NXP Semiconductors TEA1723AT/N1,118 is a compact and cost-effective Switched Mode Power Supply (SMPS) controller IC suitable for power applications up to 11 W. It is designed to operate directly from a rectified universal mains input, incorporating a 700V high voltage power switch. This device is optimized for flyback converter topologies, delivering high efficiency across the entire load range and ultra-low power consumption in no-load conditions.

The controller utilizes primary-side sensing for output voltage regulation, eliminating the need for secondary feedback circuitry and simplifying the design. At lower power levels and no-load conditions, it operates in burst mode, which minimizes audible noise and reduces power consumption to less than 12 mW at 230V AC mains input. This feature contributes to Energy Star 2.0 compliance.

Key features include a jitter function for reduced EMI, overvoltage protection (OVP), undervoltage lockout (UVLO), overtemperature protection (OTP), and soft-start functionality. The TEA1723AT/N1,118 is available in a 7-SOIC package and is suitable for surface mount applications. It operates within a supply voltage range of 8.5V to 20V and a frequency range of 22.5kHz to 50.5kHz, with an operating temperature range of -40°C to 85°C.

This IC is designed for applications requiring efficient power conversion with minimal external components, offering a cost-effective solution for low-power converters. Its integrated protective functions ensure reliable operation under various conditions.
