LNK363PN is an integrated circuit (IC) manufactured by Power Integrations.

The LNK363PN is an integrated circuit (IC) manufactured by Power Integrations. It is part of the LinkSwitch-TN family, designed for offline power supply applications.

Manufacturer:

Power Integrations

Specifications:

  • Input Voltage Range: 85 VAC to 265 VAC
  • Output Power: Up to 5 W (depending on design)
  • Switching Frequency: 66 kHz
  • Efficiency: High efficiency (meets global energy efficiency standards)
  • Output Voltage Regulation: Primary-side sensing (no optocoupler required)
  • Operating Temperature Range: -40°C to +150°C (junction temperature)
  • Package: DIP-8 (through-hole)

Descriptions:

The LNK363PN is a monolithic offline switcher IC that integrates a high-voltage power MOSFET, oscillator, simple ON/OFF control, and protection features. It is optimized for low-power, non-isolated buck and buck-boost converters.

Features:

  • Auto-Restart Protection: Includes output short-circuit, open-loop, and thermal shutdown protection.
  • Frequency Jittering: Reduces EMI emissions.
  • Line Compensation: Ensures stable output under varying input voltages.
  • Primary-Side Control: Eliminates the need for a secondary-side feedback circuit.
  • Low Component Count: Simplifies design and reduces BOM cost.

This IC is commonly used in applications such as LED drivers, auxiliary power supplies, and small offline power converters.
