Power Integrations AC/DC Converter 1.23 A 5V AC 50 V 8-Pin SOIC LNK3694G-TL

Power Integrations LNK3694G-TL is a high-efficiency AC/DC converter designed for versatile electronic power management applications. Featuring a maximum output current of 1.23 A and a 5V AC output voltage, this 8-pin SOIC device integrates a low component count switcher solution suitable for compact designs.

Operating within an input voltage range of 85V to 265V AC, the converter employs a flyback topology with switching frequency at 132kHz. It incorporates multiple protection mechanisms including output overvoltage protection (OVP), input line overvoltage (OVL), and hysteretic over-temperature protection (OTP), ensuring robust and reliable operation under varying conditions.

Its compact physical dimensions (9.83mm length, 6.6mm width, 3.68mm height) and low no-load power consumption facilitate energy-efficient designs, especially compliant with global energy efficiency regulations. The device also features extended creepage distance between the drain pin and other pins, meeting stringent safety and field reliability requirements.

Additional features include selectable device current limit, frequency jittering to reduce EMI, and a 725V MOSFET rating for excellent surge withstand capability. The 900V MOSFET rated series variant caters to industrial designs requiring extra safety margin.

This converter is applicable across industrial, consumer electronics, telecommunications, and commercial power supplies, enhancing energy efficiency and reliability in power conversion.
