DATASHEET ISL6421A Single Output LNB Supply and Control Voltage Regulator with I2C Interface for Advanced Satellite Set-top Box Designs FN9167 Rev 3.00 Mar 9, 2006 CS FB COMP VSW NC SDA ADDR SCL The ISL6421A is a highly integrated solution for providing power and control signals from advanced satellite set-top box (STB) modules to the low noise block (LNB). The internal architecture of this device contains a current-mode boost PWM and a low-noise linear regulator, along with the circuitry required for I2C device interfacing and for providing DiSEqC™ standard control signals to the LNB. A regulated output voltage is available at the output terminal (VOUT) to support the operation of the antenna port in advanced satellite STB applications.
