Monolithic Power Systems MP8128 | Demoboard EV8128-Q-00A

Description

The EV8128-Q-00A is an evaluation board designed to demonstrate the capabilities of the MP8128, a highly integrated, DiSEqC 1.x and DiSEqC 2.x compatible, low-noise block (LNB) voltage regulator. It provides efficient, low-noise power and interface signals to a satellite receiver’s LNB antenna ports. The device integrates a boost regulator and a tracking linear voltage regulator. The boost regulator provides a power source 1.1V above the LNB output voltage. The tracking linear voltage regulator provides clean power and protects the output from overloads and shorts. The MP8128 features voltage selection, overcurrent protection (OCP), an I2C interface, and a selectable 22kHz tone signal. The MP8128 offers a simple solution with a low component count, and is available in a QFN-20 (3mmx3mm) package.
