Description
The LNK305PN, part of the Power Integrations LinkSwitch-TN family, is a highly integrated, cost-effective IC specifically designed to replace linear power supplies and capacitor-fed (cap-drop) power supplies. This IC is engineered to provide a simple, reliable, and energy-efficient solution for non-isolated buck or buck-boost converter applications. By integrating a 700V power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown onto a single monolithic chip, it drastically reduces the number of external components required.
Whether you are designing low-power appliances, industrial controls, or auxiliary power supplies for consumer electronics, the LNK305PN offers exceptional energy efficiency, particularly at light loads. Its compact DIP-8 through-hole package ensures easy assembly, making it a favorite for both automated production lines and rapid prototyping on development boards.
