TNY267 Low Power Off-line Switcher IC
The TNY267 IC maintains the simplicity of the TinySwitch topology, while providing a number of new enhancements to further reduce system cost and component count, and to practically eliminate audible noise. Like Tiny Switch, a 700 V power MOSFET, oscillator, high voltage switched current source, current limit and thermal shutdown circuitry are integrated 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.
Fetures of TNY267 IC:
Fully integrated auto-restart for short circuit and open loop fault protection–saves external component costs
Built-in circuitry practically eliminates audible noise with ordinary varnished transformer
Programmable line under-voltage detect feature prevents power on/off glitches–saves external components
Frequency jittering dramatically reduces EMI (~10 dB) –minimizes EMI filter component costs
Very tight tolerances and negligible temperature variation on key parameters
High voltage powered–ideal for charger applications
High bandwidth provides fast turn on with no overshoot
Current limit operation rejects line frequency ripple Built-in current limit and thermal protection
