Automotive active noise cancellation

Описание:
This reference design is a 100-W synchronous buck converter to supply automotive loads. The IC is LM5146-Q1 in fixed frequency operation at 250 kHz to ensure low noise operation. A resistor-capacitor (RC) snubber attenuates noise in the RF band to reduce radiated emissions. To reduce system EMI, the design is prepared to either synchronize other converters (output) or be externally synchronized (input).
Возможности:

Features
  • Power stage withstands surge voltages up to 36 Vpk
  • Efficiency higher than 95% over a output current range of 5-A to 20-A (at 14-V input voltage)
  • Tight load regulation results in a low deviation (5 mV) of the output voltage over the whole range of the input voltage
  • Input filter for minimizing conducted emissions is included
