TNY268G Overview
TinySwitch™-II integrates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit and thermal shutdown circuitry onto a monolithic device. The start-up and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias winding and associated circuitry. In addition, the TinySwitch-II devices incorporate auto-restart, line undervoltage sense, and...
TNY268G Key Features
- Fully integrated auto-restart for short circuit and open loop fault
- saves external ponent costs
- Built-in circuitry practically eliminates audible noise with ordinary
- Programmable line undervoltage detect feature prevents power
- saves external ponents
- Frequency jittering dramatically reduces EMI (~10 dB)
- minimizes EMI filter ponent costs
- 132 kHz operation reduces transformer size
- Very tight tolerances and negligible temperature variation on key
- Lowest ponent count switcher solution
