The TNY279PG from Power Integrations is a flyback offline switcher in the TinySwitch®-III family, delivering up to 32 W with a 700V integrated switch. It provides galvanically isolated output, 132kHz switching, and 65% maximum duty cycle in an 8-DIP package. Built-in current limiting, open loop, over temperature, over voltage, and short circuit protection ensure robust operation across -40°C to 150°C junction temperatures.

  • Integrated 700V switch reduces external components and simplifies isolated flyback design.
  • 32 W output at 132kHz enables compact, efficient power supplies.
  • Comprehensive fault protection (current limiting, open loop, OVP, OTP, short circuit) improves reliability.
  • Wide -40°C to 150°C junction temperature range supports demanding environments.
  • EN control feature enables flexible on/off regulation.

Compact AC-DC Adapters

The integrated 700V switch and 32 W power capability make the TNY279PG ideal for compact wall adapters and chargers where board space is limited and an isolated flyback topology is required.

Standby & Auxiliary Supplies

With EN control and comprehensive fault protection, this device suits auxiliary bias supplies in appliances and industrial equipment needing reliable isolated power.

Consumer Electronics Power

The 132kHz switching frequency and 65% duty cycle support efficient flyback designs for set-top boxes, routers, and small home appliances.

Industrial Control Power

Operating from -40°C to 150°C junction temperature, the TNY279PG handles demanding thermal environments in isolated control and metering supplies.
