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

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.

September 2008
