com/tsc Single Output LNB Supply and Control Voltage Regulator with I2C Interface for Satellite Set-Top Box Designs DATASHEET FN6547 Rev 1.
00 March 17, 2011 The ISL9492 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 blocks (LNB) of a single antenna port.
It also supports DiSEqC tone generation and modulation with diagnostic status read-back.
Controlling the ISL9492 is simple via the I2C bus by writing 8 bit words onto the System Registers (SR).
The device design makes the total LNB supply design simple, efficient and compact with low external component count by integrating Boost power MOSFET, current-mode boost PWM and a low-noise linear regulator.
The current-mode boost converters provide the linear regulat...
