Overview
STR-W6735 Quasi-Resonant Topology Primary Switching Regulators Features and Benefits ▪ 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 frequency ▪ 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 ▪ 500 V / 0.
57 Ω, 160 W (120 VAC input) Continued on the next page… Package: 6-pin TO-220 Description The STR-W6735 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.
The package is a fully molded TO-220, which con...
