TNY180P

Energy-Efficient Off-Line Switcher with Enhanced Flexibility and Extended Power Range

Applications

Product Details

TinySwitch-LT incorporates a 650 V power MOSFET, oscillator, high-voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a design flexible solution with a low system cost and extended power capability.

Product Highlights:

  • 650 V rated integrated MOSFET
  • Simple ON/OFF control, no loop compensation needed
  • Selectable current limit through BP/M capacitor value
  • Higher current limit extends peak power or, in open frame applications, maximum continuous power
  • Tight I2f parameter tolerance reduces system cost; minimizes maximum overload power, reducing cost of transformer, primary clamp & secondary components
  • On-time extension—extends low line regulation range/hold-up time to reduce input bulk capacitance
  • Frequency jittering reduces EMI filter costs
