Description
STR-X6768N Off-Line Quasi-Resonant Switching Regulators .
The STR-X6768N is a quasi-resonant topology IC designed for SMPS applications.
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
▪ Standby mode Lowers input power at very light output load condition
▪ Avalanche-guaranteed MOSFET Improves sys
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
