LNK 501 PN power Integrations - AC/DC Converters 3W 85-265 VAC 4W 230VAC OCP 8DIP-7 (LNK501PN)

LNK501PN Power Integrations AC/DC Converter - 3W/4W, 85-265VAC

The LNK501PN LinkSwitch is a revolutionary AC/DC converter from Power Integrations. It's specifically designed to replace linear transformer/RCC chargers and adapters in the ≤3W universal range. This monolithic IC offers superior performance and energy efficiency at an equal or lower system cost. With up to 75% efficiency at 3W output, it significantly reduces energy consumption. The LinkSwitch boasts < 300 mW no-load consumption, leading to substantial energy savings for end-users. It integrates a 700V power MOSFET, PWM control, high voltage start-up, current limit, and thermal shutdown circuitry. This compact solution enables smaller, lighter, and more attractive power supply designs.
