Power Integrations AC/DC Converter 1.2A, 5V DC Output, 6V Min Output, Flyback, 7-Pin DIP, LinkSwitch-CV Series LNK623PG

Power Integrations LNK623PG is a highly integrated AC/DC converter designed for offline power management applications. With 1.2A output current and up to 5V DC output, the device is suited for powering a variety of electronic devices, offering energy-efficient operation with accurate constant-voltage regulation. Its compact 7-pin DIP package facilitates easy integration on the PCB.

Utilizing the LinkSwitch-CV series flyback topology, LNK623PG enables continuous or discontinuous mode operation, offering design flexibility for engineers. The converter removes the necessity for an opto-coupler and secondary CV control circuitry, simplifying the circuit layout while maintaining excellent voltage regulation performance.

The IC is self-biasing, requiring no additional bias winding supply, and compensates for temperature variations in external components. Frequency jittering in this model helps reduce the cost of EMI filters while cycle-by-cycle current limit and hysteretic thermal shutdown circuitry enhance operational safety.

Engineered with auto-restart protection, the LNK623PG reduces delivered power by over 95% in the event of short circuits or control loop faults. It meets HV creepage requirements between Drain and all other pins, features no primary or secondary current sense resistors, and boasts very low no-load consumption.

Industrial use cases for this converter include power management in consumer electronics, industrial controllers, and laboratory device supplies. Applications span AC-DC power adapters, auxiliary power supplies in HVAC systems, manufacturing equipment controllers, and embedded laboratory instrumentation.

Offers up to 1.2A maximum output current for reliable power conversion. Provides 5V DC maximum output voltage with a minimum output voltage of 6V. Features a primary-side constant-voltage control for simplified circuit design.

Utilizes a flyback topology suitable for low to medium power converter applications. Frequency jittering reduces EMI filter cost and improves efficiency. Includes self-biasing circuitry, eliminating bias winding requirements.

Auto-restart and hysteretic thermal shutdown with automatic recovery for protection. Through hole mount type with 7-pin DIP package for easy PCB integration.
