LNK564PN, Energy-Efficient Off-Line Switcher IC, DIP-8 Package Type

The LNK564PN from Power Integrations is part of the LinkSwitch-TN series, designed for low power off-line switcher applications. This IC combines a high-voltage power MOSFET switch with a power supply controller in one compact 8-pin DIP package, significantly reducing the component count and design complexity for buck, buck-boost, and flyback topologies. It is ideal for non-isolated and isolated designs up to 3W (230VAC) or 1.68W (85-265VAC).

Key Features:

• Integrated 700V MOSFET for low part count
• No-load consumption <300mW for energy savings
• Auto-restart for output short/open protection
• Accurate current limit and thermal shutdown
• ±5% internal feedback threshold
• Fully integrated soft-start limits inrush current

Additional Specifications:

• Package Type: DIP-8
• Supply Voltage: 85 – 265 VAC
• Current: 360 mA
• Type: Off-Line Switcher IC with Integrated 700V MOSFET
