LNK605DG Description

Short technical summary and product information.

The Power Integrations LNK605DG is an energy-efficient offline switcher IC that simplifies Constant Voltage/Constant Current (CV/CC) converter designs. It eliminates the need for optocouplers and secondary control circuitry, offering precise output voltage and current regulation.

 

This device features a 700V power MOSFET and operates at switching frequencies up to 85kHz, contributing to smaller transformer sizes. It provides advanced performance features such as compensation for transformer inductance tolerances, input line voltage variations, and external component temperature variations. Protection features include auto-restart for short-circuit and control loop faults, and hysteretic thermal shutdown with automatic recovery.

 

The LNK605DG is housed in a compact 8-SOIC package and is suitable for surface mount applications. It offers an output power of 4.5W for adapters and 5.1W in open-frame designs. The IC is designed to meet global energy efficiency regulations with low no-load consumption.

 

Applications include chargers for cell phones, PDAs, MP3 players, and other portable audio devices, as well as general-purpose adapters and LED drivers.
