Product Overview

The STEVAL-ISA096V1 is a demo board based on the VIPer06 monolithic converter. The VIPER06 is an offline converter with an 800V avalanche rugged power section, a PWM controller, a user defined overcurrent limit, open loop failure protection, hysteretic thermal protection, soft startup and safe auto restart after any fault condition. The VIPER06 is able to power itself directly from the rectified mains, eliminating the need for an auxiliary bias winding and offering a cost effective and space saving solution. The STEVAL-ISA096V1 is a switched mode power supply (SMPS) demonstration board. This non isolated SMPS is designed in a buck boost topology and is capable of delivering up to 2W of output over a wide input voltage range. This board also offers the user the possibility of adapting the circuit to specific needs. The SMPS generates 12V of nominal output voltage.
