Power Integrations AC/DC Converter 170 mA 50V 7-Pin Surface Mount LNK3204G-TL

Power Integrations LNK3204G-TL is a high-performance AC/DC converter in a 7-pin surface mount package, delivering a maximum output current of 170 mA at 50V. Designed for demanding power management IC applications, it supports multiple topologies including buck, buck-boost, and flyback, making it suitable for a broad range of industrial, electronic, and commercial electronics projects.

This device features a low-component count buck converter that simplifies circuitry, reduces magnetic component size and cost, and operates efficiently at a switching frequency of 66 kHz. It includes a selectable device current limit to maximize peak and continuous output power while accommodating cost-effective surface mount buck chokes. The frequency jittering mechanism helps in EMI reduction, thus easing filter complexity. The pin configuration enhances PCB heat dissipation ensuring reliability under various load conditions.

With a minimum input voltage of 85V AC and maximum input voltage of 265V AC, this converter is capable of stable operation across diverse power supply environments. It operates within a wide temperature range from -40°C to 150°C, enabling use in harsh industrial and automotive-like conditions. The device does not hold any particular approvals or automotive standards but is engineered for robust power conversion needs.

Additional features include low supply current at 141 μA to support energy efficiency, an auto-restart function that limits power delivery to 3% during fault conditions for protection, and excellent load and line regulation to ensure output stability. Its compact dimensions (9.83 mm length, 6.6 mm width, and 3.68 mm height) and surface mount design allow integration into space-constrained PCB designs.
