STRX6769 Datasheet (Allegro MicroSystems) - Off-Line Quasi-Resonant Switching Regulators

STRX6769, Off-Line Quasi-Resonant Switching Regulators

The STR-X6769 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)

STR-X6769 www.DataSheet4U.com Off-Line Quasi-Resonant Switching Regulators ▪ 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 ▪ 800 VDSS / 0.66 Ω RDS(on) ▪ Various protections  Improved s
