The LNK3317D-TL from Power Integrations is a multi-topology offline switcher supporting buck, buck-boost, and flyback configurations with isolated output. It integrates a 725V power switch, starts up at 18V, and delivers up to 12W at a 66kHz switching frequency with a 69% maximum duty cycle. Current limiting, open loop, over temperature, over voltage, and short circuit protection are included, along with EN and soft start, in a 7-lead 8-SOIC package rated for -40°C to 150°C junction temperature.
- Flexible buck, buck-boost, and flyback topologies from a single device.
- Integrated 725V switch reduces external component count.
- 12W output rating suits compact offline supplies.
- Broad protection set (current limiting, open loop, OTP, OVP, short circuit) improves reliability.
- EN and soft start support controlled power-up; wide -40°C to 150°C range.
Multi-Topology Offline Supplies
The LNK3317D-TL supports buck, buck-boost, and flyback configurations with an integrated 725V switch, giving designers flexibility to implement isolated or direct-coupled offline supplies at up to 12W from a single device.
Compact Isolated Bias Rails
In flyback configuration the device provides galvanically isolated output, with soft start and EN control supporting clean power-up in space-constrained 8-SOIC designs.
Appliance and Industrial Auxiliary Power
Current limiting, open loop, over temperature, over voltage, and short circuit protection combined with a -40°C to 150°C junction temperature range support reliable operation in demanding environments.
Low-Power Standby Supplies
At 66kHz switching frequency and 69% maximum duty cycle, the LNK3317D-TL delivers 12W for standby and auxiliary rails where compact size and fault protection are essential.
