The LNK3306D-TL from Power Integrations (LinkSwitch-TNZ series) is a multi-topology offline switcher supporting Buck, Buck-Boost, and Flyback configurations with isolated output. It integrates a 725V breakdown power switch and delivers up to 12 W at 66kHz switching frequency with 69% maximum duty cycle. An 18V start-up threshold, EN control, and soft start simplify design. Protection includes current limiting, open loop, over temperature, over voltage, and short circuit. Packaged in an 8-SOIC (7 leads) rated for -40°C to 150°C (TJ).
- Multi-topology flexibility (Buck, Buck-Boost, Flyback) supports both isolated and non-isolated designs.
- Integrated 725V switch reduces external components and BOM cost.
- Wide -40°C to 150°C junction temperature range suits high-temperature applications.
- Comprehensive protection including open loop and over temperature improves reliability.
- EN control and soft start enable flexible, controlled operation.
Isolated Flyback Supplies
The Flyback topology with isolated output and 725V breakdown supports compact isolated offline power up to 12 W. The integrated switch and 66kHz switching frequency simplify transformer-based designs.
Non-Isolated Buck Rails
In Buck configuration, the LNK3306D-TL provides a direct step-down offline supply for low-power control circuitry, with 69% maximum duty cycle and soft start for controlled startup.
Buck-Boost Conversions
For applications needing step-up/down flexibility, the Buck-Boost topology supports wide input handling. Open loop and over temperature protection improve fault tolerance.
Harsh Environment Electronics
The -40°C to 150°C (TJ) junction temperature range supports use in high-temperature environments such as appliance and industrial controls requiring isolated or non-isolated offline power.
