The new integrated circuits can deliver up to 6.1 watts in wide input range designs and up to 9.2 watts for 230 VAC open frame applications.
Designed for flyback topologies, the LinkSwitch-XT2 family offers designs with current and voltage regulation exceeding -/+3% and typical efficiency above 80%. LinkSwitch-XT2 ICs consume less than 10 mW under no-load conditions. The high operating frequency (132 kHz) allows the use of smaller power transformers, while the programmable current limiting (ILIM) function enables further transformer optimization.
The LinkSwitch-XT2 converters combine a 725V power MOSFET with control circuitry on a single silicon chip. Integrated safety and reliability features include input surge protection, hysteretic thermal shutdown for over-temperature protection, and automatic restart for output short circuit, overvoltage, and open-loop protection.
The LinkSwitch-XT2 integrated circuits come in three packages: P-package (DIP-8C), D-package (SO-8C) and G-package (SMD-8C) and are priced at $0.40 in quantities of 10,000 units.
