Автомобильная система активного шумоподавления.

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

Документация:
  • Даташит
  • Схемотехника
  • BOM
  • Топология платы
  • Тестирование

Описание:
This reference design showcases a non-synchronous boost converter with a 6-V to 18-V (36-Vpeak) input. The output voltage is programmable to 20 V-36 V using a 0-3.3 V PWM signal generated by a signal generator or MCU.
Возможности:

Features
  • Tight load regulation results in a low deviation (10 mV) of the output voltage over the whole range of the output current
  • Efficiency higher than 93% over a output current range of 0.5 A to 2 A (at 24 V output voltage)
  • Output voltage is dynamic adjustable from 6 V to 18 V output voltage
  • The already low input and output voltage ripple may be further reduced in poulating the optional input filter respective output filter
