VESUVIO® Step-Down DC-DC Converter Technology
VESUVIO® is CISSOID's platform for high-temperature, non-isolated step-down DC-DC converters. Its synchronous buck design combines the CHT-MAGMA PWM controller, CHT-HYPERION half-bridge driver and two power MOSFETs.
The LIC-VESUVIO-30 technology kit includes an evaluation board configured for a 5 V output and up to 10 W, documentation and a user license. Output voltage and power can be adapted through design customization.
