STEVAL-ISA058V1 5 W single output SMPS demonstration board based on the VIPer17 off-line high voltage converter Features ■ Input voltage range: 90 VAC to 265 VAC_RMS ■ Output voltage: 5 V ■ Maximum output current: 1 A ■ RoHS compliant Description The STEVAL-ISA058V1 demonstration board is a 5 W off-line power supply designed as an evaluation platform for the VIPer17 offline high voltage converter. STEVAL-ISA058V1 The VIPer17 features an 800 V rugged power section, PWM control, two levels of overcurrent protection, overvoltage and overload protection, hysteretic thermal protection, soft-start and safe auto-restart after fault condition removal. Burst mode operation and the very low consumption of the device help to meet standby energy saving regulations. Advance frequency jittering reduces EMI filter cost. A brown-out function protects the switch mode power supply when the rectified input voltage level is below the normal minimum level specified for the system. A high voltage startup circuit is embedded in the device. August 2009 Doc ID 16146 Rev 1 1/4 www.st.com 4 & # * /HM.4# .4# #/. * #/.
