LNK606DG

The LNK606DG is a monolithic power conversion IC from Power Integrations, designed for offline switch-mode power supplies. It is part of the LinkSwitch-II series, which combines a high-voltage power MOSFET with a power supply controller into one package. This integration simplifies the design of low-power, isolated, and non-isolated flyback applications, typically used in chargers, adapters, and other compact power supply solutions.
Key features include excellent efficiency, low standby power consumption, and robust protection mechanisms, such as over-temperature, over-voltage, and short-circuit protection. The LNK606DG supports both primary-side regulation (PSR) and secondary-side regulation (SSR), enabling precise control and eliminating the need for an opto-isolator in PSR designs.
The device operates with high frequency, reducing the size of external components, and is available in a compact SMD package, making it suitable for space-constrained applications. Its design eases compliance with energy efficiency standards like Energy Star, thanks to its high efficiency and low standby power characteristics.
