General Description

The STR-X6737 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.

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.
  • Auto-Standby mode  Lowers input power at very light output load condition.
  • Avalanche-guaranteed MOSFET  Improves system-level reliability and does not require VDSS derating.
  • 500 VDSS / 0.36 Ω RDS(on).
  • Various protections  Improved system-level reliability ▫ Pulse-by-pulse drain overc.
