Sanken STR2W153D - 90W Flyback Switching Regulator IC

The STR2W153D from Sanken Electric is a high-performance 90-watt flyback switching regulator IC designed for isolated AC-DC power supply applications. Featuring a 650V breakdown voltage and integrated switching topology, this component delivers reliable power conversion with comprehensive protection features including current limiting, over-load, over-temperature, and over-voltage safeguards.

Key Features:

  • 90W power output with flyback topology
  • 650V breakdown voltage for robust isolation
  • 60kHz to 74kHz switching frequency range
  • Wide supply voltage range: 8.1V to 32V
  • 15.3V start-up voltage
  • 74% duty cycle capability
  • Comprehensive fault protection (current limiting, over-load, over-temperature, over-voltage)
  • Operating temperature range: -20°C to 115°C
  • RoHS compliant

Applications: Ideal for consumer electronics, industrial power supplies, LED drivers, and any application requiring reliable isolated AC-DC conversion with built-in protection.

Package: TO-220F-6L (TO-220-6 Full Pack with formed leads) for easy through-hole mounting.
