STMicroelectronics, Inc. Development Boards, Kits, Programmers - Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPS STEVAL-ISA140V1

The STEVAL-ISA140V1 is a 15W evaluation board designed for isolated flyback converter applications using the VIPER37HE integrated circuit. It operates with an AC main input voltage range of 100 V_AC to 265 V_AC and supports mains frequencies of 50 Hz and 60 Hz. The board provides a typical output voltage of 12 V with a maximum output current of 1.25 A and an output ripple voltage of 50 mV. The evaluation board is optimized for compact size, making it suitable for applications requiring a small footprint. It features an active mode efficiency of 78% and consumes only 50 mW in standby mode at 230 V_AC. The ambient operating temperature can reach up to 60 ¬8C, and the product is RoHS compliant, ensuring it meets environmental standards. This evaluation board serves as a practical tool for engineers looking to develop and test isolated auxiliary power supplies.
