The Power Integrations LNK4114D-TL is a LinkSwitch™-4 isolated flyback offline switcher controller that drives an external power switch. It supports up to 15 W at a 65kHz switching frequency and operates from a 5V to 16.5V Vcc supply. Protections include over temperature, over voltage, and short circuit. Packaged in an 8-SOIC, it is rated for -25°C to 125°C junction temperature.
- External-switch architecture gives designers flexibility in selecting the power MOSFET.
- 15 W output supports compact isolated flyback designs.
- 65kHz switching frequency enables small magnetic components.
- Over temperature, over voltage, and short circuit protection improve reliability.
- Compact 8-SOIC package saves board space.
