The STEVAl-ISA171V1 implements a 15 W power supply designed in quasi resonant flyback topology for a wide-range AC input voltage. Its key features are its small size and minimal bill of material, high efficiency and low standby consumption. The core of the application is the VIPER35, the quasi-resonant offline high voltage converter from the VIPerPLUS product family.
The VIPER35 integrates an 800 V rugged power MOSFET with PWM current-mode control.
Extremely low consumption under no-load conditions is ensured thanks to burst mode operation that reduces the average switching frequency and minimizes all frequency-related losses.
The VIPER35 operates in quasi resonant mode.

Wide input voltage range: 90 VAC to 264 VAC
Output voltage: 12 V
Output current: 1.25 A
Rated output power: 15 W
Quasi resonant operation
Input power standby @ 230 VAC: < 30 mW
Active mode efficiency: > 82%
