LNK 623 PN power Integrations - AC/DC Converters 6.5W 85-265 VAC 3W 230VAC OCP 8DIP-7 (LNK623PN)

LNK623PN Power Integrations AC/DC Converter: LinkZero™-LP with Ultra-Low Standby Power

The LNK623PN AC/DC Converter from Power Integrations introduces LinkZero™-LP technology, setting new benchmarks for energy efficiency. This advanced controller automatically enters and wakes from a no-load mode, consuming less than 5 mW from AC power. This remarkable standby consumption effectively rounds to zero based on IEC 62301 standards, making it immeasurable on most power meters. It provides accurate constant voltage from 5% to full load, thanks to its precisely specified FEEDBACK (FB) pin voltage reference. Operating power is derived directly from the DRAIN pin, eliminating the need for external start-up circuitry. Furthermore, an internal jittered oscillator significantly reduces both quasi-peak and average EMI, simplifying design and lowering costs. The LNK623PN is an ideal choice for highly efficient, compact power supply solutions.
