Product Description

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.

IC Details

The MP8124 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 MP8124 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 MP8124 is available in a 14-pin QFN (2mmx3mm) package.
