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).

Key Features

  • Wide Input Supply Voltage Range : 8V to 16V.
  • Output Current Limit of 550mA with 45ms Timer.
  • Low Noise LNB Output Voltage (13.3V and 18.3V by SEL Pin).
  • ±3% High Accuracy for 0mA to 500mA Current Output.
  • Push-Pull Output Stage Minimizes 13.3V to 18.3V and 18.3V to 13.3V Output Transition Time.
  • Output Short Circuit Protection.
  • Over-Temperature Protection.
