LNK304PN Datasheet – LinkSwitch, Off-Line Switcher IC

Part Number: LNK304PN

Function: Lowest Component Count, Energy-Efficient Off-Line Switcher IC

Package: P ( DIP 8-B ), G ( SMD-8B ) Type

Manufacturer: Power Integrations, Inc


LNK304PN Link Switcher IC


The LNK304PN is Off-Line Switcher IC.

LinkSwitch-TN is specifically designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360 mA output current range at equal system cost while offering much higher performance and energy efficiency.

LinkSwitch-TN devices integrate a 700 V power MOSFET, oscillator, simple On/Off control scheme, a high-voltage switched current source, frequency jittering, cycle-by-cycle current limit and thermal shutdown circuitry onto a monolithic IC.


LNK304PN datasheet pinout


0. Cost Effective Linear/Cap Dropper Replacement

1. Lowest cost and component count buck converter solution

2. Fully integrated auto-restart for short-circuit and open loop fault protection – saves external component costs

3. LNK302 uses a simplified controller without auto-restart for very low system cost

4. 66 kHz operation with accurate current limit – allows low cost off-the-shelf 1 mH inductor for up to 120 mA output current

5. Tight tolerances and negligible temperature variation

6. High breakdown voltage of 700 V provides excellent input surge withstand
