Overview
g n i h tors c t i a Sw egul R STR-W6753 Universal-Input/58 W Off-Line QuasiResonant Flyback Switching Regulator The STR-W6753 is a quasi-resonant regulator specifically designed to satisfy the requirements for increased integration and reliability in switch-mode power supplies.
It incorporates a primary control and drive circuit with an avalanche-rated power MOSFET.
The regulator exhibits only low-level high-frequency EMI noise because of soft switching of the MOSFET close to ground (bottom point).
A bottom-skip function minimizes an increase of operational frequency during light loads to improve system efficiency over the entire load range.
Covering the power range from below 120 watts for a 230 VAC input, or 58 watts for a universal input (85 to 264 VAC), this device can be used in a range of applications, from DVD and VCR players to ac adapters for cellular phones and digital cameras.
An auto-standby function, which is internally triggered by sensing on time, reduces power consum...
