VIPER12ADIP-E low power AC/DC adapter demonstration board (suitable for the STEVAL-ILL002V1)
Features
■Minimum AC input voltage = 88 Vrms
■Maximum AC input voltage = 265 Vrms
■Max output power = 4.1 W
■Output voltage = 4.5 V
■Max output current = 900 mA
■Efficiency (at full load and 230 Vac) = 70 %
■Efficiency (at full load and 115 Vac) = 70 %
Description
The STEVAL-ISA011V1 demonstration board is a low power (4.1 W output), general purpose adapter. The design is based on the VIPER12ADIP-E monolithic device which, in the same package, integrates the high voltage power switch and the basic control function needed for a current mode flyback converter.
The board can handle a wide range AC input voltage, from 88 Vac to 265 Vac, with one output voltage of 4.5 V delivering a maximum output current of 900 mA.
The main applications for this board are auxiliary power supplies and wall-plug adapters.
