The TNY280PN from Power Integrations is a TinySwitch®-III Flyback offline switcher delivering 36.5W in an isolated configuration. It integrates the power switch and offers a 700V breakdown voltage, 65% maximum duty cycle, and 132kHz switching frequency. Packaged in an 8-DIP (7-lead) format, it includes EN control and comprehensive fault protection across a -40°C to 150°C junction range.
- Integrated power switch simplifies isolated flyback designs and reduces BOM count.
- 700V breakdown voltage supports direct offline mains operation.
- 36.5W output power suits adapters, chargers, and auxiliary supplies.
- EN control enables efficient regulation and standby management.
- Full fault protection (OCP, OVP, OTP, SCP) for reliable operation.
Isolated AC-DC Power Supplies
The TNY280PN's Flyback topology and isolated output suit galvanically isolated offline supplies up to 36.5W, such as adapters and auxiliary power modules.
Higher-Power Adapters and Chargers
With 36.5W output power and an integrated switch, the device supports compact adapter designs with reduced external component count.
Standby and Bias Rails
The EN control feature supports efficient regulation for standby and bias supply rails in larger systems.
Harsh-Environment Enclosures
A -40°C to 150°C junction range allows operation in thermally demanding or outdoor-rated equipment.
Fault-Tolerant Designs
Built-in current limiting, over voltage, over temperature, and short circuit protection support robust, reliable operation.
