■ Based on LNBH24 in QFN32 package
STEVAL-CBL006V1
Description
The demonstration board STEVAL-CBL006V1
implements a DC-DC converter based on the
device LNBH24. It gives good performance in a
simple and cheap way and minimum external
components are required. It includes all the
functions that allow the design of a dual tuner
STBs with supplying/interfacing function in
accordance with the international standards. It
also includes an I²C bus interface and, thanks to a
fully integrated step-up DC-DC converter, it works
with a single input voltage supply in the range of 8
V to 15 V.
