TNY266G

AC DC Converters, Offline Switchers Overview

The TNY266G is a TinySwitch-II family member from Power Integrations, designed as an enhanced, energy-efficient offline switch. It integrates a 700 V power MOSFET with high-voltage current source and PWM controller in a single monolithic IC. The device operates at a switching frequency of 132 kHz to minimize transformer size. It supports wide-range AC input voltages from 85 VAC to 265 VAC. The component delivers a maximum continuous output power of 9.5 W in open-frame configurations at 230 VAC input. It utilizes a surface-mount SMD-8 package for compact PCB integration.

AC DC Converters, Offline Switchers Feature Summary

• Integrates automatic restart protection against output short circuits and control loop open faults to reduce external component costs.
• Features programmable line voltage undervoltage detection to prevent output glitches during power cycling events.
• Employs frequency jittering techniques to significantly lower electromagnetic interference emissions.

AC DC Converters, Offline Switchers Applications

• Low-power adapters and chargers for mobile phones, PDAs, and digital cameras
• Standby power supplies for personal computers and televisions
• Built-in power sources for DVD players, set-top boxes, and home appliances

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'G' indicates the surface-mount SMD-8 package variant rather than the through-hole DIP version. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure design specifications align with the 9.5 W open-frame power rating at 230 VAC input conditions.

AC DC Converters, Offline Switchers Selection Notes

Select this component for designs requiring a compact surface-mount solution with integrated fault protection. It serves as a direct replacement for legacy linear regulators in low-power applications. Consider the 132 kHz operating frequency when designing magnetic components to optimize size and efficiency. Verify thermal management requirements for the SMD-8 package under maximum load conditions.

AC DC Converters, Offline Switchers Part Context

This part belongs to the TinySwitch-II series, representing the second generation of monolithic off-line switches from Power Integrations. It succeeds the original TinySwitch family by offering higher power density and improved efficiency. The series is engineered to replace bulky linear power supplies with smaller, more efficient switched-mode alternatives suitable for consumer electronics.
