Power Integrations AC/DC Converter 360mA 50V 7-Pin PDIP LNK3206P

Power Integrations LNK3206P AC/DC Converter is a versatile power management integrated circuit designed for flyback topology power supplies. It offers a maximum output current of 360 mA and a maximum output voltage of 50 V in a compact 7-pin PDIP through-hole package. This device supports buck, buck-boost, and flyback topologies, enabling designers to create low component count, cost-efficient switching power supplies with optimal performance.

Operating at a switching frequency of 66 kHz, the LNK3206P features an accurate current limit function with selectable device current limits, allowing for flexible power delivery and the use of low-cost inductors and magnetics. Its frequency jittering capability helps reduce EMI filter complexity, making it easier to meet regulatory standards.

The IC includes an auto-restart functionality that protects against short-circuit and open-loop faults by limiting power delivery to just 3% of maximum during faults, thereby enhancing system reliability. The device also benefits from a wide operating temperature range of -40°C to 150°C and accommodates input voltages from 85V to 265V AC, making it suitable for various industrial, commercial, and consumer electronic applications.

Its through-hole PDIP package with 7 pins simplifies PCB layout and heat sinking, improving mechanical robustness during manufacturing. Low quiescent supply current at 141μA contributes to energy-saving designs, especially in standby modes. The maximum duty cycle of 69% and high current limit extend both peak and continuous output power capabilities, maximizing efficiency for power supply designs.
