Product Summary
The ISL6405ERZ is a highly integrated voltage regulator and interface IC. THe device is specifically 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 ISL6405ERZ is comprised of two independent current-mode boost PWMs and two low-noise linear regulators along with the circuitry required for 22kHz tone generation, modulation and I2C device interface. The ISL6405ERZ makes the total LNB supply design simple, efficient and compact with low external component count.
