LNBH26LS Overview
Key Specifications
Package: QFN
Mount Type: Surface Mount
Pins: 24
Operating Voltage: 12 V
Description
Intended for analog and digital DUAL satellite receiver/Sat-TV, Sat-PC cards, the LNBH26LS is a monolithic voltage regulator and IC interface, assembled in QFN24 (4x4) specifically designed to provide the 13/18 V power supply and the 22 kHz tone signaling to the LNB down-converter in the antenna dishes or to the multi-switch box. In this application field, it offers a complete solution for dual tuner satellite receivers with extremely low component count, low power dissipation together with simple design and I²C standard interfacing.
Key Features
- Complete interface between then LNB and I²C bus
- Built-in DC-DC converter for single 12 V supply operation and high efficiency (typ. 93% @ 0.5 A)
- Selectable output current limit by external resistor
- Compliant with main satellite receiver output voltage specification (8 programmable levels)
- Accurate built-in 22 kHz tone generator suits widely accepted standards
