Description
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. STEVAL-CBL003V1
