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).
