The LNK3202D-TL from Power Integrations is a LinkSwitch-TN2 offline switcher IC integrating a 725V power MOSFET for non-isolated Buck, Buck-Boost, and Flyback designs. Operating at 66kHz with a 69% maximum duty cycle, it delivers a compact, low-component-count solution in an 8-SOIC (7-lead) package. Built-in current limiting, over temperature, over voltage, and short circuit protection enhance reliability across a -40°C to 125°C junction temperature range.
- Integrated 725V MOSFET reduces external component count and board space.
- Supports Buck, Buck-Boost, and Flyback topologies for design flexibility.
- Comprehensive protection (current limiting, OTP, OVP, short circuit) improves reliability.
- 66kHz switching with 69% max duty cycle enables compact magnetics.
- Wide -40°C to 125°C junction temperature range suits demanding environments.
Non-Isolated AC-DC Bias Supplies
The LNK3202D-TL delivers a compact non-isolated bias supply for appliances and industrial controls. Its integrated switch and 725V breakdown rating allow direct offline operation with minimal external parts.
Buck Converter Auxiliary Rails
Using the Buck topology, this LinkSwitch-TN2 device generates low-voltage rails from the AC mains. The 66kHz switching frequency and 69% max duty cycle support efficient step-down conversion in a small 8-SOIC footprint.
Buck-Boost for Wide Output Range
When the output voltage must exceed or fall below the input, the Buck-Boost topology provides flexibility. Built-in current limiting and short circuit protection safeguard the supply under fault conditions.
Flyback for Low-Power Non-Isolated Loads
For applications needing a simple flyback arrangement without galvanic isolation, the LNK3202D-TL integrates the switch and control, reducing BOM cost while retaining over temperature and over voltage protection.
Harsh-Environment Electronics
With an operating junction temperature range of -40°C to 125°C, the device suits demanding thermal environments in metering, HVAC, and smart-home electronics.
