Description
The LNK6666 LinkSwitch-HP is a highly integrated 90W Off-Line Switcher IC that combines a high-voltage power MOSFET and advanced controller into a single compact package. Designed for high-efficiency AC-DC power conversion, it supports Continuous Conduction Mode (CCM) and Primary Side Regulation (PSR), eliminating the need for an optocoupler in many power supply designs while delivering excellent efficiency, low standby power consumption, and reliable output regulation.
The LNK6666 features an advanced multi-mode PWM control architecture that automatically adjusts switching frequency and peak current to maintain stable output voltage across varying load conditions. It incorporates comprehensive protection features including over-voltage protection (OVP), under-voltage protection (UV), over-temperature protection (OTP), overload protection, short-circuit protection with auto-restart, and programmable current limiting, making it suitable for demanding industrial and commercial applications.
Ideal for engineers, power supply designers, repair technicians, and embedded hardware developers, the LNK6666 simplifies high-performance SMPS designs while reducing component count, PCB size, and overall system cost. It is widely used in industrial power supplies, adapters, battery chargers, consumer electronics, and automation equipment requiring efficient and reliable offline power conversion.
