LNBH25SPQR LNB supply and control IC with step-up and I²C interface

Intended for analog and digital satellite receivers/Sat-TV and Sat-PC cards, the LNBH25S is a monolithic voltage regulator and interface IC, assembled in QFN24L (4x4 mm) specifically designed to provide 13/18 V power supply and 22 kHz tone signaling 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 interface.
