STR-W6735, Quasi-Resonant Topology Primary Switching Regulators

STR-W6735 Quasi-Resonant Topology Primary Switching Regulators .
The STR-W6735 is a quasi-resonant topology IC designed for SMPS applications.

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 frequency ▪ Standby burst mode operation => Lowers input power at very light output load condition ▪ Avalanche-guaranteed

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 ca
