Description

The PB51 is a 1.5A, 300V power booster amplifier designed to provide voltage and current gain for a small-signal, general purpose operational amplifier. By using the PB51 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 PB51 can 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 PB51 is a hybrid product design housed in a space saving, electrically isolated 12-pin PowerSIP package that lends itself to high density circuit board layouts. Target applications include high voltage instrumentation, electrostatic transducers and deflection, and programmable power supplies. The PB58A is the A grade version offering enhanced performance in the areas of output current (2A), slew rate (75V/µs) and offset voltage.
