The STEVAL-ISA129V1 demonstration board is a 16 V - 280 mA application set in non isolated flyback topology using the VIPer16, a new off-line high voltage converter by STMicroelectronics. The VIPer16 features an 800 V avalanche rugged power section, PWM operation at 115 kHz with frequency jittering for lower EMI, limiting current with adjustable set point, on-board soft-start, and safe auto-restart after a fault condition. Moreover, the VIPer16 can work with or without the auxiliary winding. In the former case, it can reach very low standby consumption (< 50 mW at 265 Vac), while in the latter the IC is supplied by an internal current generator, thus eliminating the cost of the transformer auxiliary winding. https://elecena.pl/product/8157485/steval-isa129v1-16-v-280-ma-non-isolated-off-line-high-voltage-converter-based-on-the-viper16h 2017-03-26 https://elecena.pl/product/8157485/steval-isa129v1-16-v-280-ma-non-isolated-off-line-high-voltage-converter-based-on-the-viper16h 2017-09-09 https://elecena.pl/product/8157485/steval-isa129v1-16-v-280-ma-non-isolated-off-line-high-voltage-converter-based-on-the-viper16h 2020-06-05 https://elecena.pl/product/8157485/steval-isa129v1-16-v-280-ma-non-isolated-off-line-high-voltage-converter-based-on-the-viper16h 2021-04-02 https://elecena.pl/product/8157485/steval-isa129v1-16-v-280-ma-non-isolated-off-line-high-voltage-converter-based-on-the-viper16h 2022-06-11 https://elecena.pl/product/8157485/steval-isa129v1-16-v-280-ma-non-isolated-off-line-high-voltage-converter-based-on-the-viper16h 2022-06-24 https://elecena.pl/product/8157485/steval-isa129v1-16-v-280-ma-non-isolated-off-line-high-voltage-converter-based-on-the-viper16h 2024-12-11 https://elecena.pl/product/8157485/steval-isa129v1-16-v-280-ma-non-isolated-off-line-high-voltage-converter-based-on-the-viper16h 2025-01-16 https://elecena.pl/product/8157485/steval-isa129v1-16-v-280-ma-non-isolated-off-line-high-voltage-converter-based-on-the-viper16h 2025-04-18
