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.\nA regulated output voltage is available at the output terminal (VOUT) to support the operation of the antenna port in advanced satellite STB applications. The regulated output may be set to either 13V or 18V by use of the voltage select command bit (VSEL) through the I2C bus. Additionally, to compensate for the voltage drop in the coaxial cable, the voltage may be increased by 1V with the line length compensation bit (LLC) feature. The device can be put into a standby mode by means of the enable bit (EN), this disables the PWM and Linear regulator combination and helps conserve power.\nThe input to the linear regulator is derived from the current mode boost converter, such that the required voltage is the sum of the output voltage and the linear regulator drop (1.0V typical). This ensures that the power dissipation is minimized and maintains a constant voltage drop across the linear pass element, while permitting an adequate voltage range for tone injection.\nThe device is capable of providing 450mA (typical). The overcurrent limit is either digitally or resistor programmable.
