STRW6735 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
500 V / 0.57 Ω, 160 W (120 VAC input)

STRW6735 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.
