Package
Description
Intended for analog and digital satellite
receivers/Sat-TV and Sat-PC cards, the LNBH25
is a monolithic voltage regulator and interface IC,
assembled in QFN24 4x4 specifically designed to
provide the 13/18 V power supply and the 22 kHz
tone signalling 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 and low power
dissipation together with a simple design and I²C
standard interfacing.
