The Power Integrations TNY276PN is a flyback offline switcher from the TinySwitch-III series, delivering up to 19 W with a 700V integrated switch. Housed in a 7-lead 8-DIP package, it operates at 132kHz with 65% maximum duty cycle and includes current limiting, open loop, over temperature, over voltage, and short circuit protection across a -40°C to 150°C junction temperature range.
- Integrated 700V switch simplifies isolated flyback design.
- 19 W output supports adapters and auxiliary supplies.
- Broad fault protection including over voltage and short circuit.
- Wide -40°C to 150°C junction range for demanding thermal environments.
- Through-hole 7-lead 8-DIP package for robust assembly.
Isolated AC-DC Adapters
The TNY276PN integrates the switch and controller in a 7-lead 8-DIP package, delivering up to 19 W for isolated flyback adapters. The 700V breakdown rating provides margin for universal AC input designs.
Auxiliary and Bias Supplies
With 132kHz switching and 65% maximum duty cycle, this flyback switcher provides efficient isolated bias rails for appliances and industrial controls, protected by over voltage and open loop detection.
Home Appliance Electronics
The -40°C to 150°C junction temperature range supports reliable operation in white goods and HVAC control boards requiring isolated low-power rails.
