The latest addition to its growing
portfolio of ICs designed for low-wattage power supplies, has been
introduced by Power Integrations.
LinkSwitch-XT targets applications in which tight regulation of
output voltage and current are key design priorities. It supports
universal-input (85Vac to 265Vac) chargers and adapters with output
levels of up to 4 watts, and may be used in open-frame applications
up to 9W (230Vac).
With EcoSmart technology, LinkSwitch-XT is ideal for use in chargers
and adapters designed to comply with energy-efficiency standards
for external power supplies. Its simple ON/OFF control scheme enables
a high level of efficiency even at light loads, reducing no-load
consumption to less than 300mW; and with the use of a transformer
having a bias winding, this is further reduced to less than 50mW.
LinkSwitch-XT features a 700V power MOSFET together with control
circuitry on a single silicon die.

Integrated safety and reliability features include hysteretic thermal
shutdown for over-temperature protection, as well as auto-restart
for output shortcircuit and open-loop protection. It is the latest
addition to Power Integrations' portfolio of low-power ICs, which
are designed to replace inefficient power supplies built around line-frequency
transformers.
