Summary and Features
• Highly integrated IC realizes a significant reduction in component count
• Main transformer resets with a 700 V MOSFET and no reset winding
• Input power < 1 W (with standby loaded to 0.5 W and the main supply off)
• Meets Blue Angel 5 W requirement (measures 4.1 W, at specified conditions)
• Passes EN55022 B conducted EMI limits, with more than 10 dB of margin
• Simple voltage mode control provides good transient response & regulation
