Intersil ISL6405 Dual Output LNB Supply and Control Voltage Regulator Datasheet
The ISL6405 is a highly integrated voltage regulator and interface IC designed for supplying power and control signals from advanced satellite set-top box (STB) modules to the low noise blocks (LNBs) of two antenna ports. The device comprises two independent current-mode boost PWMs and two low-noise linear regulators, along with circuitry for 22kHz tone generation, modulation, and I2C device interface. It simplifies LNB supply design by reducing the external component count while maintaining efficiency and compactness.
