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 sup-

ply voltage. This allows the user the benefits of using

his standard 12V or 24V buss without the need to de-

sign a high voltage supply to power the op amp. The

SMPS voltage is adjustable from 50-350V, allowing for

op amp output voltages up to 340V. External phase

compensation provides the user with the flexibility to

tailor gain, slew rate and bandwidth for a specific ap-

plication. The unique design of this amplifier provides

extremely high slew rates in pulse applications while

maintaining low quiescent current. The output stage

is well protected with a user defined current limit. Safe

Operating Area (SOA) must be observed for reliable

operation.
