MP8126 550mA, 8V-to-14V Input, LNB-Power Supply and Control-Voltage Regulator The Future of Analog IC Technology DESCRIPTION The MP8126 is a voltage regulator designed to provide efficient, low-noise power to a satellite receiver’s RF LNB (Low Noise Block) converter. It connects using a coaxial cable through a link that is compatible with the European EUTELSAT specification (DiSEqC) 1.x that receives instructions from a dedicated controller. The MP8126 integrates a current-mode boost regulator followed by a tracking linear regulator. The boost regulator provides a clean and quiet power source that will not contaminate the lownoise RF signal as it is down-converted to the receiver. The tracking linear regulator protects the output against overloads or shorts. The MP8126 provides a number of features described in the DiSEqC, including voltage selection of horizontal or vertical LNB polarization directions, and selectable VOUT compensation for substantial voltage drops on long coaxial cable. In accordance with DiSEqC, the part can detect a 22kHz signal and output a shaped signal. The MP8126 is available in a thermallyenhanced TSSOP16EP and 24-pin QFN (4X4mm) packages.
