Descriptions

The PT4105ESOP is a highly integrated offline switcher IC designed for low-power applications such as LED drivers, auxiliary power supplies, and smart home devices. It combines a high-voltage power MOSFET with a controller in a compact ESOP package, simplifying design and reducing component count.

Features

  • Integrated 700V Power MOSFET – Reduces external component requirements.
  • Primary-Side Regulation (PSR) – Eliminates the need for an optocoupler or secondary feedback circuit.
  • Auto-Restart Protection – Safely recovers from fault conditions.
  • Low Standby Power Consumption – Meets energy efficiency standards.
  • Compact ESOP Package – Enhances thermal performance with an exposed pad.
  • Wide Input Voltage Range – Supports universal AC input (85V – 265V).
