Микросхемы и комплектующие STEVAL-ISA183V1

Оценочная плата , квази-резонансный обратноходовой преобразователь на 3 выхода 16Вт

The STEVAL-ISA183V1 from STMicroelectronics is a 16W triple output quasi resonant flyback converter for air conditioning applications using VIPer35LD. The STEVAL-ISA183V1 evaluation board implements a 16W triple output power supply designed in quasi-resonant flyback topology, specifically designed as an auxiliary PSU for air conditioning systems. The core of the application is the VIPER35LD high voltage converter from the VIPerPlus product family which integrates an 800V rugged power MOSFET with a quasi-resonant PWM current-mode control. The power supply provides an isolated 12V / 1A output a two non-isolated outputs, 15V /200mA and 5V / 200mA respectively. Other key features include high conversion efficiency, the extremely low consumption at no-load and at minimum operative output conditions and excellent EMI performance using a low cost input filter.

• AC main input voltage range from 175VAC to 275VAC
• 12V-1A (isolated), 15V-200mA (non-isolated), 5V-200mA (non-isolated), continuous operation
• < 50mW at no-load condition and < 1.5W input power at minimum operative output power (0.91W)
• Efficiency at full load is greater than 81%
• EN55022 class B conducted EMI compliant, using a low cost input filter
