DESCRIPTION
The MP400FC combines a high voltage, high speed precision power op amp with a supply voltage boost
function in an integrated thermally conductive module. The voltage boost function uses a switch mode power
supply (SMPS) to boost the input power supply voltage. This allows the user the benefits of using a standard
12 V or 24 V bus without the need to design a high voltage supply to power the op amp. The SMPS voltage is
adjustable from 50-350 V, allowing for op amp output voltages up to 340 V. External phase compensation pro-
vides the user with the flexibility to tailor gain, slew rate and bandwidth for a specific application. The unique
design of this amplifier provides extremely high slew rates in pulse applications while maintaining low quies-
cent current. The output stage is well protected with a user defined current limit. Safe Operating Area (SOA)
must be observed for reliable operation.
