STR-W6753 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
650 V / 1.70 Ω
Various protections  Improved system-level reliability Continued on the next page…

STR-W6753 Description

The STR-W6753 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.
