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 singe 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 Isup2/supC device interface. The device makes the total LNB supply design simple, efficient and compact with low external component count.brbr The current-mode boost converters provides the linear regulator with input voltage that is set to the final output voltages, plus typically 0.8V to insure minimum power dissipation across each linear regulator. This maintains constant voltage drop across the linear pass element while permitting adequate voltage range for tone injection.brbr 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 Isup2/supC using the VTOP and VBOT bits or set the Isup2/supC to the lower range i.e., 13V/14V, and switch to higher range i.e., 18V/19V, with the SELVTOP pin. All the functions on this IC are controlled via the Isup2/supC bus by writing 8 bits words onto the System Registers (SR). The same register can be read back, and five Isup2/supC bits will report the diagnostic status. Separate enable command sent on the Isup2/supC bus provides for standby mode control for the PWM and linear combination, disabling the output and forcing a shutdown mode. The output channel is capable of providing 750mA of continuous current. The overcurrent limit can be digitally programmed to four levels.brbr The External modulation input EXTM can ac
