STRX6768N Key Features

  • Quasi-resonant topology IC  Low EMI noise and soft switching
  • Bottom-skip mode  Improved system efficiency over the entire output load by avoiding increase of switching frequency
  • Standby mode  Lowers input power at very light output load condition
  • Avalanche-guaranteed MOSFET  Improves system-level reliability and does not require VDSS derating
  • 800 VDSS / 1.00 Ω RDS(on)
  • Various protections  Improved system-level reliability

STRX6768N Description

The STR-X6768N is a quasi-resonant topology IC designed for SMPS applications. It shows lower EMI noise characteristics than conventional PWM solutions, especially at greater than 2 MHz. It also provides a soft-switching mode to turn on the internal MOSFET at close to zero voltage (VDS bottom point) by use of the resonant characteristic of primary inductance and a resonant capacitor.
