The MP8124GD-Z is a highly integrated voltage regulator designed to provide efficient, low-noise power and interface signals to the low-noise block (LNB) of a satellite receiver. It provides a 22kHz tone signal output, which is compatible with DiSEqC 1.x.The MP8124GD-Z integrates a current-mode boost regulator followed by a tracking linear regulator. Also, it has output voltage selection and a 22kHz tone shaper from an external signal. 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 and shorts.Full protection features include over-current protection (OCP), short-circuit protection (SCP), boost over-voltage protection (OVP), and over-temperature protection (OTP), offering a simple solution with a low component count and high efficiency.The MP8124GD-Z is available in a 14-pin QFN (2mmx3mm) package. 9icnet Electronics is an authorized Monolithic Power Systems distributor.
