Description

The STEVAL-CBL005V1 LNB power supply

demonstration board implements a DC-DC

converter based on the LNBH23 device. The

LNBH23 is an LNB supply and control IC with

an LNB on a dish antenna for reception of satellite

TV signals.

The LNBH23 is an integrated solution for

supplying/interfacing satellite LNB modules in

accordance with international standards.

This solution is simple, inexpensive, shows very

good performance and has a low external

component count.

The LNBH23 demonstration board includes an

generator that is factory-trimmed to comply with

widely accepted standards, and can be controlled

through the DSQIN pin (TTL compatible). This

allows immediate DiSEqC™ data encoding.

Due to the fully integrated step-up DC-DC

converter, it works with a single input voltage

supply source ranging from 8 V to 15 V.
