Description

This reference design shows the performance of a non-isolated automotive power supply for a driving monitoring system for the electronic control unit (ECU). The reference design includes our power portfolio with nine power sockets.

Features
  • Non-isolated multirail output power
  • Small solution size of 40.7 mm x 37.8 mm
  • EMI friendly as it contains an input filter
  • Thermal performance of ΔT < 40 °C
