The LNK4023D-TL from Power Integrations is a LinkSwitch-4 flyback switcher for isolated offline applications, rated at 10W. It drives an external switch from a 5V to 16.5V Vcc supply at a 65kHz switching frequency. Over temperature, over voltage, and short circuit protection are integrated, in an 8-SOIC package rated -25°C to 125°C junction temperature.
- 10W flyback rating for isolated offline supplies.
- 65kHz fixed switching frequency simplifies magnetic design.
- Over temperature, over voltage, and short circuit protection for robust operation.
- 8-SOIC package for space-efficient layouts.
- Part of the LinkSwitch-4 series for a consistent design platform.
Medium Low-Power Isolated Supplies
The LNK4023D-TL is a flyback switcher rated for 10W, suited to isolated offline supplies for auxiliary, bias, and small load rails.
8-SOIC Compact Layouts
The 8-SOIC package supports space-efficient converter designs with standard assembly handling.
Fixed 65kHz Operation
A 65kHz switching frequency provides a defined operating point for transformer and filter design in the flyback stage.
Robust Fault Handling
Over temperature, over voltage, and short circuit protection help safeguard the converter under fault conditions.
