LNK304PN LinkSwitch-TN IC | Off-Line Switcher DIP-8

The LNK304PN is a member of the LinkSwitch-TN family by Power Integrations, designed for highly efficient, low-cost non-isolated flyback and buck power supplies. It integrates a 700V power MOSFET, oscillator, simple on/off control scheme, and fault protection into a single DIP-8 package.

Key Features

• Part Number: LNK304PN
• Manufacturer: Power Integrations
• Package: DIP-8 (Through-Hole)
• Output Power: Up to 360 mW (open frame) / 260 mW (sealed adapter)
• Input Voltage: 85–265 VAC (universal input)
• Integrated 700V MOSFET
• Auto-restart for fault protection (overload, short circuit)
• Frequency jittering for low EMI
• Extremely low no-load power consumption (<50 mW)
• Replaces discrete designs with fewer components

Applications

• Standby power supplies
• LED driver circuits
• Low-power chargers and adapters
