This evaluation board implements a DC-DC converter based on the LNBH25S device. It is used to power LNBs inside dish antennas to receive satellite TV signals.
The LNBH25S is an integrated solution for supplying / interfacing satellite LNB modules in accordance with international standards. This simple solution offers a complete solution for dual tuner satellite receivers and provides good performance at low cost using a low external component count.
The LNBH25S evaluation 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), which 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 16 V.
