STR-W6765 Quasi-Resonant Topology Primary Switching Regulators

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 po.

STR-W6765 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
