This paper presenst CISSOID's new high temperature chips for Power Management and Motor Control in automotive, oil & gas, aerospace and industrial applications. High temperature DC-DC reference designs, called respectively ETNA, VESUVIO™ and EREBUS™, have been announced recently. These Buck (step-down) DC-DC converters are built with proven CISSOID products as active components rated from −55°C up to 225°C. These DC-DC converters can have input voltages from 6V up to 50V. The output voltage can be adjusted from 10% up to 90% of the input voltage. Power efficiencies in excess of 90% above 200°C have been demonstrated. VESUVIO™ and EREBUS™ are based on MAGMA PWM controller, HYPERION half-bridge driver and two power transistors to implement a synchronous Buck converter. For high voltage and power levels, new Silicon-Carbide devices allow operating at high junction temperatures. They enable high power modules with higher densities in terms of size and weight. Having power drivers able to operate very close to...
