NV9574S2P1-RA - GaNSense™ Integrated Flyback Controller IC

The NV9574S2P1-RA from Navitas Semiconductor is a high-performance GaN-based AC-DC flyback controller designed for isolated power conversion applications. This advanced GaNSense™ IC integrates primary-side control with secondary-side synchronous rectification (SR), delivering superior efficiency and reliability in a compact 7-ESOP surface-mount package.

Key Features & Benefits

  • 700V Breakdown Voltage - Robust high-voltage capability for universal AC input designs
  • Dual Switching Frequencies - Selectable 164kHz or 225kHz operation for design flexibility
  • Wide Supply Range - 6.5V to 77V operating range with 13.5V start-up voltage
  • Comprehensive Protection - Built-in over-load, over-temperature, over-voltage, and short-circuit fault protection
  • Extended Temperature Range - Reliable operation from -40°C to 125°C (TA)
  • High Efficiency - Integrated switches and secondary-side SR minimize losses
  • Compact Footprint - 7-lead ESOP package (8-SOIC compatible, 3.90mm width) with exposed pad for thermal management

Typical Applications

  • AC-DC power adapters and chargers
  • Industrial power supplies
  • Telecom and networking equipment
  • Consumer electronics power conversion
  • Smart home and IoT devices
  • LED lighting drivers
