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. It is a simple and complete solution for dual tuner satellite receivers and provides high performance at low cost with a low external component count.
The LNBH25S evaluation board includes an I2C bus interface and an internal 22 kHz tone generator which is factory trimmed and can be controlled by the DSQIN pin (TTL compatible), allowing 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.
