The MP400 is a “board-level module” power op amp that integrates the performance of a high speed op amp with a switch mode power supply. The result is a high voltage driver that delivers adjustable output voltages from 50V-350V off of low, standard buss supplies of 12V, 24V and 48V. With the ability to internally generate high levels of output voltage, the MP400 allows designers to bypass having to design or purchase an external high voltage power supply... Both the high voltage output of the MP400, and the applications drive circuitry – typically a piezo element – can operate of the same standard system supply. The result is a reduction in board space, as well as potential savings on operating costs. The MP400’s ability to adjust the voltage output level is made possible through use of a single, external ¼ watt resistor from the set pin (R SET) to ground. The only input required by the boost supply are the VIN source, the input/output filter capacitor and the VBOOST set resistor (RSET). The voltage boost adjustment is independent of VIN. |
