STRX6737 Overview
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.
STRX6737 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
