TNY267PG

AC DC Converters, Offline Switchers Overview

The TNY267PG is a TinySwitch-II AC/DC converter from Power Integrations, designed for off-line flyback applications. It integrates a 700 V power MOSFET, oscillator, and control circuitry into an 8-pin DIP package. The device supports an input voltage range of 85 VAC to 265 VAC, delivering 12 W at 85-265 VAC and 19 W at 230 VAC. Key electrical parameters include a switching frequency of 132 kHz, a maximum duty cycle of 65%, and a quiescent supply current of 365 uA. It operates within a temperature range of -40°C to +150°C.

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'PG' confirms the through-hole DIP-8 packaging variant. Confirm RoHS compliance status via the manufacturer's latest documentation. Check for any product change notices regarding marking or packing updates. Ensure design-in compatibility with existing thermal management solutions given the 150°C junction temperature rating.

AC DC Converters, Offline Switchers Selection Notes

Select this component for designs requiring integrated high-voltage switching in a through-hole format. The 132 kHz frequency allows for compact transformer sizes while minimizing audible noise. Consider the 365 uA supply current for standby power efficiency requirements. Evaluate the 65% maximum duty cycle against the required voltage conversion ratio.

AC DC Converters, Offline Switchers Part Context

This part belongs to the TinySwitch-II family, which combines power switching and control functions. It serves as an alternative to traditional PWM controllers plus discrete MOSFETs. The DIP-8 package facilitates manual assembly or wave soldering processes compared to surface-mount variants.
