General Description
Power Operational Amplifiers
Features
Low Cost Wide Common Mode Range Standard Supply Voltage Single Supply: 10 V to 50 V Output Current - 150 mA Continuous Output Voltage 50-350 V 350 V/S Slew Rate 200 kHz Power Bandwidth
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 his standard 12 V or 24 V buss 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 provides 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 quiescent current. The output stage is well protected with a user defined current limit. Safe Operating Area (SOA) must be observed for reliable operation.
