PMP9382, High-Efficiency Low Vin 30W Boost Converter for Automotive Applications (E-Call) Reference Design. PMP9382 is a low Vin boost converter utilizing the automotive grade LM3478Q-Q1 controller. This design starts at a diode drop above the minimum input voltage of 2.97V (3.4V) to a maximum of 6V in. Once the power supply is enabled and output is present, this design will work down to 2V input minimum, supplying an output voltage of 10V at 3A. The Switching frequency is set to 400 kHz
