The Power Integrations LNK3604P is an isolated flyback offline switcher from the LinkSwitch-XT2 series with an integrated switch and a 725V breakdown voltage rating. It delivers up to 7.3W at a 132kHz switching frequency with a 69% maximum duty cycle. Current limiting, over temperature, and over voltage protection are included. Supplied in an 8-DIP package rated for -40°C to 150°C junction temperature.
- 725V breakdown rating supports offline flyback designs with margin.
- Integrated switch reduces external component count for compact low-power supplies.
- Current limiting, over temperature, and over voltage protection improve reliability.
- 132kHz switching frequency and 69% max duty cycle support efficient low-power conversion.
- -40°C to 150°C junction temperature range suits thermally demanding applications.
Low-Power Isolated Supplies
With 7.3W output and an isolated flyback topology, the LNK3604P suits low-power AC-DC bias and auxiliary supplies requiring galvanic isolation.
Compact 8-DIP Designs
The 8-DIP package with integrated switch enables compact isolated flyback converters with minimal external components.
High-Temperature Operation
A junction temperature range of -40°C to 150°C supports reliable operation in thermally demanding environments.
Protected Low-Power Conversion
Current limiting, over temperature, and over voltage protection help safeguard the converter under fault conditions.
