The Power Integrations LNK6774K-TL is a flyback offline switcher from the LinkSwitch-HP series featuring an integrated switch and 725V breakdown rating. It delivers up to 39 W with switching from 120kHz to 136kHz and a 64% maximum duty cycle, packaged in a 12-BESOP with exposed pad. Comprehensive fault protection and a -40°C to 150°C junction range suit it to robust isolated power supplies.
- Integrated switch and 725V breakdown simplify isolated flyback designs.
- Up to 39 W output supports medium-power AC-DC applications.
- Exposed-pad 12-BESOP package improves thermal performance.
- Broad fault protection (over load, OVP, OTP, short circuit, current limiting) enhances reliability.
- Wide -40°C to 150°C junction range for demanding environments.
Medium-Power AC-DC Power Supplies
The LNK6774K-TL delivers up to 39 W in an isolated flyback topology, suited to adapters and embedded supplies requiring higher output than entry-level designs. The 725V breakdown rating offers margin for universal input.
Industrial and Appliance Power
With over load, over voltage, over temperature, and short circuit protection, this LinkSwitch-HP device supports robust isolated supplies in appliances and industrial controls.
Compact High-Density Designs
The 12-BESOP exposed-pad package aids thermal dissipation, while the 120kHz–136kHz switching range supports compact transformer designs.
Harsh-Environment Systems
A -40°C to 150°C junction temperature range enables reliable operation in demanding thermal conditions.
