... Rset MP400U http://www.cirrus.com General DescriPtion The MP400FC combines a high voltage, high speed precision power op amp with a supply voltage boost function in an integrated thermally conductive mod- ule. The voltage boost function uses a switch mode power supply (SMPS) to boost the input power supply voltage ...

... Long loops in these paths pick up noise and increase the likelihood of LC interactions and oscillations. sMPs oPeration The MP400FC is designed to operate off of a standard voltage rail. Typi- cal values include The addition of the on-board SMPS eliminates the need to design or purchase a high voltage power supply. The ...

... An external input capacitor is required. This capacitor should be at least 100 µF. therMal consiDerations For reliable operation the MP400FC will require a heatsink for most applications. When choosing the heatsink the power dissipation in the op amp and the SMPS MOSFET switch (Q2) are both considered. The power dissipation of the op amp is determined in the same manner as any power op amp ...
