STR-ADAS-PREREGULATOR-GEVK: Strata Enabled Flexible ADAS Power Solution

The STR-ADAS-PREREGULATOR-GEVK is an optimized power management solution for automotive systems such as Infotainment or ADAS with an I2C programmable output voltage between 0.6V-3.3V and a fixed 5V output. The system boasts a high efficiency up to 98% and its adaptability allows for implementation in several high performance applications. The key featured components are the NCV6357 Adapative-On-Time and programmable buck converter, the NCV881930 low quiescent buck synchronous controller and the 40V, high thermal performance and compact NVMFS5C460NL MOSFETs. Thanks to the Strata visual interface, users can not only monitor telemetry data, such as, voltage, current, efficiency or temperature; but also adjust the output voltage. Strata ready-to-use laboratory environment enables a fast system and component evaluation. The development kit include the STR-ADAS-PREREGULATOR-GEVB, the Strata plug-in board, USB cable and load resistors. See the Strata webpage at www.onsemi.com/strata for more details!
