The Power Integrations LNK3302D-TL from the LinkSwitch-TNZ series is an offline switcher supporting Buck, Buck-Boost, and Flyback topologies with up to 3W output. It integrates a 725V power switch, reducing external component count. Operating at 66kHz with 69% maximum duty cycle, it includes soft start and EN control. Current limiting, open-loop, over-temperature, over-voltage, and short-circuit protection safeguard operation across a -40°C to 150°C junction temperature range in an 8-SOIC package.
- Integrated 725V switch reduces BOM and board space.
- Multi-topology support (Buck, Buck-Boost, Flyback) adds design flexibility.
- Up to 3W output suits compact bias and auxiliary supplies.
- Broad protection set including over-temperature and short circuit.
- -40°C to 150°C range supports demanding environments.
Compact Isolated Supplies
The LNK3302D-TL integrates a 725V switch, enabling isolated flyback designs up to 3W in a small 8-SOIC footprint.
Buck and Buck-Boost Rails
Multi-topology support lets designers implement buck or buck-boost conversion for auxiliary rails from a single part.
Appliance and Metering Power
Over-temperature and over-voltage protection plus a -40°C to 150°C range support harsh-environment designs.
Low-Power Bias Supplies
Soft start and EN control simplify startup and enable control in standby and bias applications.
