                LNB Supply with Tone Repeater/Synthesizer and Programmable Cable Drop Compensation
                GENERAL DESCRIPTION

                This device is a high efficiency boost power supply which converts 12V nominal input to 14V/19V nominal output, plus a linear regulation stage for tone signal transmission. It can repeat the external 22kHz tone input symmetrically or synthesize a 22kHz tone signal upon external on/off control.

                Pulsing on its EN initiates -1V/+0.4V drop compensation, making it suitable for where external surge absorbing devices are used at the output and for long cable installation.

                The SGM41286 is available in Green TDFN-3×3-8L and SOIC-8 (Exposed Pad) packages. It operates over an ambient temperature range of -40 to +85.
