TOP232P** is a member of the **TOPSwitch-GX** family of integrated power switching ICs manufactured by **Power Integrations (PI)**.

The TOP232P is a member of the TOPSwitch-GX family of integrated power switching ICs manufactured by Power Integrations (PI). It combines a high-voltage power MOSFET, PWM controller, and protection features into a single package, making it suitable for offline power supply applications.

Specifications:

  • Input Voltage Range: 85V AC to 265V AC (universal input)
  • Output Power (Max): Up to 12W (depending on design and cooling conditions)
  • Switching Frequency: 132 kHz (fixed)
  • Integrated MOSFET: 700V, avalanche-rated
  • Maximum Duty Cycle: 78% (typical)
  • Current Limit: Adjustable via external resistor
  • Operating Temperature Range: -40°C to +150°C
  • Package: DIP-8 (Through-hole) or SMD-8 (Surface-mount)

Key Features:

  • Integrated High-Voltage MOSFET: Eliminates the need for a separate switching transistor.
  • Advanced Protection Features: Includes over-temperature, over-voltage, and current limiting.
  • Frequency Jittering: Reduces EMI emissions.
  • Auto-Restart Protection: Safely recovers from fault conditions.
  • Programmable Features: Adjustable current limit and soft-start.
  • Low Standby Power Consumption: Suitable for energy-efficient designs.

Applications:

  • AC/DC power supplies (adapters, chargers)
  • Standby power supplies
  • LED drivers
  • Industrial and consumer electronics

The TOP232P is designed for compact, cost-effective, and reliable power conversion solutions. For detailed design guidelines, refer to the official Power Integrations datasheet.
