Description
Intended for the Japanese market for digital dual
satellite receivers/Sat-TV, and Sat-PC cards, the
LNBH30 is a monolithic voltage regulator and
interface IC, assembled in QFN16 (4x4 mm)
specifically designed to provide the power supply
to the LNB down-converter in the antenna dish or
to the multi-switch box. In this application field, it
offers a complete solution with extremely low
component count, low power dissipation together
with simple design and I²C standard interfacing.
