Wireless modem module for automotive

This reference design uses an LM63635-Q1 synchronous buck converter to output either a 3.3-V or 5-V rail. The bus converter switches at 2.1 MHz, and the load converters (TPS62810-Q1) switch at 2.2 MHz. The system is designed for telematics control unit power. Easily configurable jumpers allow users to enable and disable the bus converter, load converters and load switches for up to 3-A maximum load at each output.

  • 12-V input, bus converter with selectable 3.3-V or 5-V outputs
  • Four selectable load switch outputs with 3-A maximum load
  • All switching converters operate above 2 MHz to avoid AM band
  • Very good output ripple with and without load (<1%)
  • Built for easy testability using configurable jumpers and test points

  • Даташит
  • Схемотехника
  • BOM
