Renesas Electronics Corporation Highly Integrated Dual Output LNB Supply and Control Voltage Regulator with I2C Interface ISL6422BERZ-T

Description
The ISL6422B 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 consists of two independent currentmode boost PWMs and two low-noise linear regulators 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 Two independent current-mode boost converters provide the linear regulators with input voltages that are set to the final output voltages, plus typically 0.8V 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.brbr 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 can be controlled in two ways, full control from Isup2/supC using the VTOP1, VTOP2 and VBOT1, VBOT2 bits or set the Isup2/supC to the lower range ie 13V/14V and switch to higher range ie 18V/19V with the SELVTOP1, SELVTOP2 pins. 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 four bits per output will report the diagnostic status. Separate enable commands sent on the Isup2/supC bus provide independent standby mode control for each PWM and linear combination, disabling the output into shutdown mode. Each output channel is capable of providing 750mA of continuous current. The overcurrent limit can be digitally programmed.brbr The Ex
