Single Output LNB Supply and Control Voltage Regulator
General Description
The RT5070 is a highly integrated voltage regulator and interface IC, specifically design for supplying power and control signals from advanced satellite set-top box (STB) modules to the LNB down-converter in the antenna dish or to the multi-switch box.
The device is consists of the independent current-mode boost controller and low dropout linear regulator for the LNB power.
The RT5070 has fault protection (over-current, over-temperature and under-voltage lockout).
The RT5070 are available in a SOP-8 (Exposed Pad) package to achieve optimized solution for thermal dissipation.
