MP8128
DESCRIPTION The MP8128 is a highly integrated voltage regulator designed to provide efficient, lownoise power and interface signals to a satellite receiver’s low noise block downconverter (LNB) at the antenna port. The device provides a 22k Hz tone signal and a standard I2C interface for satellite receivers. It is patible with both Di SEq C 1.x and Di SEq C 2.x. The MP8128 integrates a boost regulator followed by a tracking linear regulator. The boost regulator provides a power source that exceeds the final output voltage by 1.1V, while the tracking linear regulator provides low noise power and protects the output against overloads or shorts. The device provides a number of features including voltage selection, over-current protection (OCP), and 22k Hz tone signal control. The MP8128 offers a simple solution with a low ponent count and high efficiency. The MP8128 is available in QFN-20 (3mmx3mm) package. FEATURES - Di SEq C 1.x and Di SEq C 2.x patible - Integrated I2C Interface - 8V to 14V...
