500mA, LNB Power Supply and Control Regulator Evaluation Board
EV8124-D-00A Evaluation Board is designed to demonstrate the capability of MP8124. MP8124 is a highly integrated voltage regulator to provide efficient, low noise power and the interface signals to a satellite receiver’s Low Noise Block (LNB). It generates 22kHz tone signal compatible with DiSEqC 1.x.
The MP8124 integrates a current-mode boost regulator followed by a tracking linear regulator. The boost regulator provides a clean power source which is 1V higher than the final output voltage while the tracking linear regulator protects the output against overloads or shorts.
The MP8124 provides a number of features including bus voltage selection, over current protection and 22kHz tone shaper from external signal. It offers a simple solution with low component count and high efficiency.
The MP8124 is available in a 14-pin QFN (2X3mm) package.
