STEVAL-ISA006V1

STEVAL-ISA006V1 reference design is an auxiliary power supply based on the VIPer12AS monolithic device and can be used to produce multiple non isolated positive or negative voltage outputs. This solution is based on an offline discontinuous current mode flyback converter without isolation between input and output. The flyback topology allows the exploitation of the VIPer12AS current capability when compared with the buck converter based power supply. To ensure power supply low cost, the isolation between input and output is not provided. This greatly simplifies the transformer design and production. The VIPer12AS incorporates the PWM controller with a 60KHz internal oscillator and the vertical Power MOSFET switch in a SO 8 package. The presented power supply has four variants. All the variants have been incorporated in the presented reference board through different assembly options.

• Switch mode general purpose power supply
• Input voltage 90V to 264V ac at 50/60Hz
• Main Output (regulated) 5V, 500mA at 50/ 60Hz
• Second output 15V,200mA
• Output power (pick) 5.5W
