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.
