ISL6401 Synchronizing Current Mode PWM for Subscriber Line Interface Circuits (SLICs)
intersil ISL6424 handbook
The ISL6424 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 (LNBs) of two antenna ports. The device 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 device makes the total LNB supply design simple, efficient and compact with low external component count. Two independent current-mode boost converters provide the linear regulators with input voltages that are set to the final output voltages, plus typically 1.2V to insure minimum power dissipation across each linear regulator. This maintains constant voltage drops across each linear pass element while permitting adequate voltage range for tone injection. The final regulated output voltages are available at two output terminals to support simultaneous operation of two antenna ports for dual tuners. The outputs for each PWM are set to 13V or 18V by independent voltage select commands (VSEL1, VSEL2) through the I2C bus. Additionally, to compensate for the voltage drop in the coaxial cable, the selected voltage may be increased by 1V with the line length compensation (LLC) feature. All the functions on this IC

intersil ISL6425 handbook
The ISL6425 is a highly integrated solution for supplying power and control signals from advanced satellite set-top box (STB) modules to the low noise block (LNB). This device is comprised of 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. The regulated output may be set to either 13V or 18V by use of the voltage select command (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 (LLC) feature. An enable command sent on the I2C bus provides standby mode control for the PWM and linear combination, disabling the output to conserve power. A current-mode boost converter provides the linear regulator with an input voltage that is set to the required output voltage, plus 1.2V (typ.) to insure minimum power dissipation. This maintains a constant voltage drop across the linear pass element, while permitting an adequate voltage range for tone injection. The device is capable of providing 750mA (typ.).
intersil ISL6423B handbook
The ISL6423B 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 (LNBs) of single antenna ports. The device consists of a current-mode boost PWM and a low-noise linear regulator along with the circuitry required for 22kHz tone generation, modulation, and I2C device interface. The device simplifies the total LNB supply design, making it simple, efficient, and compact with a low external component count. The current-mode boost converter provides the linear regulator with an input voltage that is set to the final output voltages, plus typically 0.8V to ensure minimum power dissipation across each linear regulator. This maintains a constant voltage drop across the linear pass element while permitting an adequate voltage range for tone injection. The final regulated output voltage is available at output terminals to support the operation of an antenna port for single tuners. The outputs for each PWM can be controlled in two ways, full control from I2C using the VTOP and VBOT bits, or set the I2C to the lower range i.e., 13V/14V, and switch to the higher range i.e., 18V/19V, with the SELVTOP pin. All the functions on this IC are controlled via the I2C bus by writing 8-bit words onto the System Registers (SR). The same register can be reused.
