LNK304GN,Energy-Efficient Off-Line Switcher,DIP-7,120mA

The LNK304GN - DIP-7 is a member of the LinkSwitch-TN family from Power Integrations, designed to provide an energy-efficient and cost-effective solution for off-line switchers. The device integrates a 700V power MOSFET, oscillator, high-voltage switched current source, frequency jittering, and various protection mechanisms into a monolithic IC. With its ability to operate at an average frequency of 66 kHz, the LNK304GN delivers up to 120mA output current in a buck converter topology, making it an ideal choice for applications such as appliances, industrial controls, and LED drivers.

The LNK304GN operates across a universal input voltage range from 85V to 265V AC, ensuring compatibility with global power standards. It features advanced protection mechanisms, including over-temperature shutdown, auto-restart, and short-circuit protection, ensuring reliable operation under various fault conditions. Additionally, its minimal no-load power consumption makes it suitable for eco-friendly designs, meeting energy efficiency standards like Energy Star and EU requirements.

Packaged in a compact DIP-7 form, the LNK304GN is designed for space-constrained applications. Its integrated frequency jittering reduces EMI emissions by approximately 10 dB, simplifying the design and lowering the cost of external filters. The LNK304GN is perfect for use in buck, buck-boost, and flyback converters, providing excellent line and load regulation with a reduced component count.
