ST LNBH24LQTR

转换器，模拟和数字式卫星信号 STB 接收器/SatTV8V ~ 15V13.3V，18.2V

Overview

Intended for analog and digital DUAL satellite receivers/Sat-TV, Sat-PC cards, the LNBH24LQTR is a monolithic voltage regulator and interface IC, assembled in QFN 5x5 ePAD, specifically designed to provide the 13 / 18 V power supply and the 22 kHz tone signaling for two independent LNB down-converters in the antenna dishes and/or multi-switch box. In this application field, it offers a dual tuner STBs complete solution with extremely low component count, low power dissipation together with simple design and I2C standard interfacing.

Features
