The Power Integrations LNK6776E from the LinkSwitch™-HP series is an isolated Flyback offline switcher with an integrated 725V breakdown power switch. It delivers up to 88 W with a 120kHz to 136kHz switching frequency and 64% maximum duty cycle. Built-in current limiting, over load, over temperature, over voltage, and short circuit protection ensure safe operation across a -40°C to 150°C junction temperature range in a 7-SSIP package.
- High 88 W output power in an isolated Flyback topology.
- Integrated 725V power switch reduces external components.
- Comprehensive protection: current limiting, over load, over temperature, over voltage, and short circuit.
- Wide -40°C to 150°C junction temperature range for demanding applications.
- 120kHz to 136kHz switching frequency for compact transformer design.
High-Power Isolated Flyback Supplies
Delivering up to 88 W with a 725V integrated switch, the LNK6776E suits isolated Flyback designs for adapters, chargers, and industrial power supplies. The 120kHz to 136kHz switching range and 64% max duty cycle support efficient transformer utilization.
Industrial and Appliance Power
The -40°C to 150°C junction temperature range enables reliable operation in harsh environments. Over voltage, over load, over temperature, current limiting, and short circuit protection safeguard the system under fault conditions.
