LNB power supply demonstration board based on the LNBH23L DiSEqC 1.X compliant (QFN)
  • active Active

The STEVAL-CBL007V1 demonstration board is intended to provide information and suggestions on the correct use of the LNBH23L device.

The LNBH23L is an integrated solution for supplying/interfacing satellite LNB modules. Simple and inexpensive, it provides good performance while minimizing the number of external components required.

It includes all functions needed for LNB supply and interfacing, and is compliant with international standards. It includes an I2C bus interface and, due to the fully integrated step-up DC-DC converter, functions with a single input voltage supply from 8 V to 15 V.
