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.
