The 900V versions of the LinkSwitch-XT2 IC family are optimised for high efficiency, enabling designs to easily meet Energy Related Products (ErP) limits. LinkSwitch-XT2 power supplies use less than 30mW when unloaded and have high conversion efficiency across the load range.
This makes the new devices suitable for IoT and Home and Building Automation (HBA) systems which spend substantial time in active standby monitoring radio or networking interfaces.
The ICs feature selectable current limit and fully integrated auto-restart for short circuit and open-loop protection. The use of frequency jittering greatly reduces EMI, and devices easily meet high voltage creepage and clearance requirements between the DRAIN and all other pins both on the PCB and on the package.
Senior Product Marketing Manager, Silvestro Fimiani commented: “These switching power ICs enable designers of three-phase utility meters, motors, industrial auxiliary power supplies, appliances and IoT/HBA sensors and actuators to realise a truly ‘one-world’ power supply that meets the reliability expectations of users everywhere.
“For example, OEMs addressing the burgeoning market in India for high quality consumer products suffer a continuous stream of electrically damaged and returned products that must be serviced or replaced. 900V LinkSwitch-XT2 switcher ICs provide effective and inexpensive protection with a commensurate reduction in operating and product-support costs.”
