High-Efficiency Low Vin 30W Boost Converter for Automotive Applications (E-Call) Reference Design
Description
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.
Features
