W6765 Overview
The STR-W6765 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 operation 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.
W6765 Key Features
- Quasi-resonant topology IC ⇒ Low EMI noise and soft switching
- Bottom-skip operation ⇒ Improved system efficiency over the entire output load by avoiding increase of switching frequen
- Standby burst mode operation ⇒ Lowers input power at very light output load condition
- Avalanche-guaranteed MOSFET ⇒ Improves systemlevel reliability and does not require VDSS derating
- 800 V / 1.8 Ω, 52 to 110 W (Universal/230 Vac input)
