The Power Integrations TNY274PG is a flyback offline switcher from the TinySwitch-III series with an integrated switch and 700V breakdown rating. It delivers up to 11 W at 132kHz switching frequency with a 65% maximum duty cycle, housed in a 7-lead 8-DIP package. Comprehensive fault protection and a wide -40°C to 150°C junction range make it a dependable choice for compact isolated power supplies.
- Integrated switch simplifies flyback design and reduces external component count.
- 700V breakdown rating provides headroom for universal AC input flyback topologies.
- 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.
- 132kHz switching enables compact magnetic components at 11 W output.
Compact AC-DC Adapters
The TNY274PG integrates the switch and control into an 8-DIP package, making it well suited to space-constrained flyback adapters up to 11 W. The 700V breakdown rating provides margin for universal AC input.
Standby and Auxiliary Supplies
With EN control and comprehensive fault protection, this TinySwitch-III device supports reliable isolated bias supplies in appliances and industrial equipment.
Chargers and Small Power Supplies
The 132kHz switching frequency and 65% max duty cycle enable compact transformer designs for low-power isolated chargers.
Harsh-Environment Designs
A -40°C to 150°C junction temperature range supports use in demanding thermal environments where isolated flyback conversion is required.
