Power Integrations AC/DC Converter 1.2 A 5 V DC 6 V 7-Pin DIP LNK624PG

Power Integrations LNK624PG AC/DC Converter is a highly integrated 7-pin DIP packaged power management IC designed for low power constant-voltage (CV) AC-DC conversion applications. Its 1.2 A maximum output current at 5 V DC output and 11 W output power capability make it ideal for various electronics requiring reliable power supply solutions.

This device operates with a maximum input voltage of 265V AC and a minimum input voltage of 85V AC, accommodating a broad input voltage range. Utilizing flyback topology, it offers stable output power with a switching frequency of 100 kHz, incorporating frequency jitter to minimize electromagnetic interference, reducing upstream filter costs.

The LNK624PG features self-biasing, eliminating the need for a bias winding supply and secondary CV control circuitry, significantly simplifying the power supply design. It integrates a 725V power MOSFET with on/off state control, cycle-by-cycle current limiting, and hysteretic thermal shutdown with automatic recovery for enhanced device protection.

The converter supports continuous and discontinuous modes of operation, allowing flexible design choices. Its maximum duty cycle is 54%, ensuring efficient power conversion. The device is suitable for operation in harsh conditions, functioning reliably from -40°C up to 150°C.

Additional protection mechanisms include auto-restart to reduce output power by over 95% during short-circuits or control faults and compliance with high-voltage creepage requirements for safety. With a compact footprint and through-hole mount type, it is suitable for a wide range of industrial, electronic component, telecommunications, and consumer device applications requiring durable, energy-efficient AC/DC power conversion.
