LNK501PN Power Integrations Off-Line Switcher IC

LNK501PN Power Integrations Off-Line Switcher IC

is a highly integrated off-line switcher IC from Power Integrations, designed to enable compact, efficient, and cost-effective power supplies. Housed in a 7-pin DIP (Dual Inline Package), it is part of the LinkSwitch-TN family, which integrates a high-voltage power MOSFET, oscillator, current limit, and thermal shutdown circuitry into a single package.

This IC is commonly used in low-power AC-DC applications up to 360 mW (non-isolated) or 185 mW (isolated), such as utility meters, industrial sensors, home automation systems, and standby power supplies. Its key advantage lies in reducing external component count and delivering high energy efficiency in minimal board space.
