Targeted for set-top-box applications, the ISL6405 dual-output low-noise block (LNB) downconverter supply and control voltage regulator IC saves board space and parts count. It provides independent power and functional control for two LNB modules located on the antenna of a two-channel satellite receiver system. This dual-output device includes two current-mode boost pulse-width modulation (PWM) controllers and two low-noise linear regulators. It uses an industry-standard I2C interface to control internal functions. Each of the two independent power and control circuits puts out either 13 or 18 V dc for LNB power. The unit operates from a single 8- to 14-V dc supply, and no separate logic supply is needed. It features high output current of 750 mA per channel, simultaneously. The device is available in a 28-pin EPSOIC (ISL6405EEB) or 32-pad QFN (ISL6405ER) package. The ISL6405EEB and ISL6405ER cost $2.20 and $2.35 each, respectively, in 100-unit quantities.
