LNB power supply demonstration board based on the LNBH23

This demonstration board implements a DC-DC converter based on the LNBH23 device. It is used to power LNBs inside dish antennas to receive satellite TV signals.

The LNBH23 is an integrated solution for supplying/interfacing satellite LNB modules in accordance with international standards This simple solution provides good performance at low cost using a low external component count.

The LNBH23 demonstration board includes an I2C™ bus interface and the internal 22 kHz tone generator which is factory trimmed and can be controlled by the DSQIN pin (TTL compatible.

This allows immediate DiSEqC™ data encoding.

Thanks to a fully integrated step-up DC-DC converter, it functions with a single input voltage supply source ranging from 8 V to 15 V.

Key Features

  • Integrated DC-DC converter
  • I2 C bus interface for the IC control and diagnostics
  • Single input supply voltage: from 8 V to 15 V
  • User-friendly graphical interface (\"LNBxxx control suite\" software included in the kit)
