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.
