The Power Integrations LNK3771D-H003-TL is an isolated flyback offline switcher with secondary-side synchronous rectification and an integrated power switch. Rated at 725V breakdown and 7 W output, it switches at 66kHz and includes current limiting, over temperature, over voltage, short circuit, and UVLO protection. Housed in a 16-SOIC (14-lead) package, it operates from -40°C to 105°C.
- Integrated power switch simplifies isolated flyback designs and reduces external component count.
- 725V breakdown rating supports universal AC input margins.
- Secondary-side SR topology improves rectification in isolated outputs.
- Comprehensive fault protection (current limiting, OVP, OTP, SCP, UVLO) enhances reliability.
- Wide -40°C to 105°C range suits demanding environments.
Compact Isolated AC-DC Adapters
The 725V breakdown rating and 7 W power capability suit low-power isolated flyback adapters operating from universal AC mains, with secondary-side SR improving rectification.
Standby and Auxiliary Supplies
With 66kHz switching and integrated switch, this device supports auxiliary bias supplies needing isolated output in a 16-SOIC package.
Industrial Control Bias Rails
The -40°C to 105°C operating range and comprehensive fault protection (current limiting, OVP, OTP, SCP, UVLO) fit control-board bias supplies.
Metering and Smart-Energy Modules
Isolated flyback topology with secondary-side SR delivers a regulated isolated rail for metering front-ends within a compact footprint.
