General Description

The RT5007 is a highly integrated voltage regulator and interface IC, specifically designed for supplying power and control signals from advanced satellite Set-Top Box (STB) modules to the Low Noise Block (LNB) down converter in the antenna dish or to the multi-switch box.

The device consists of an independent current-mode Boost controller and low a dropout linear regulator and the circuitry required for 22kHz tone generation to support one-way DiSEqCTM communications.

All the functions and the LNB output voltages (8 programmable levels) can be controlled via the I2C bus.

Key Features

  • Wide Input Supply Voltage Range : 8V to 16V.
  • Wide Output Supply Current Range : 0mA to 500mA.
  • Adjustable Output Current Limit Up to 500mA with 5ms Timer.
  • LNB Voltages (8 Programmable Levels).
  • ±4.5% High Accuracy of LNB Voltage for 0mA to 500mA Current Output.
  • Fault Latch for OTP, OCP, UVLO.
  • Built-in 22kHz Tone Generator One-Way DiSEqCTM Communication.
  • Adjustable Rising/Falling Time via External Capacitor.
  • 2-Wire Serial I2C Compatible Interface.
