STR-W6756 datasheet


The STR-W6756 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.


Features and Benefits

1. Quasi-resonant topology IC – Low EMI noise and soft switching

2. Bottom-skip mode –  Improved system efficiency over the entire output load by avoiding increase of switching frequency

3. Auto-Standby mode – Lowers input power at very light output load condition

4. Avalanche-guaranteed MOSFET – Improves system-level reliability and does not require VDSS derating

5. 650 V / 0.73 Ω

6. Various protections – Improved system-level reliability
