 PB50 Data Sheet

The PB50 is a 2A, 200V power booster amplifier designed to provide voltage and current gain for a small signal, general purpose operational amplifier. By using the PB50 power booster within the feedback loop of a driver amplifier, the resulting composite amplifier has the accuracy of the driver with the extended output voltage range and current capability of the booster. The PB50 can also be used without a driver amplifier in some applications, requiring only an external current limit resistor to function properly.

Compensation is not required for most driver/gain configurations, but can be accomplished with a single external capacitor. Although the power booster can be configured quite simply, enormous flexibility is provided through the choice of driver amplifier, current limit, supply voltage, voltage gain and compensation.

The PB50 is a hybrid product design housed in an electrically isolated, hermetically sealed, 8-pin TO-3 metal package. Targeted applications include high voltage instrumentation, electrostatic transducers and deflection and programmable power supplies.
