Power Booster Amplifier

DESCRIPTION

FEATURES

The PB51 is a high voltage, high current ampliﬁer de-

signed to provide voltage and current gain for a small

signal, general purpose op amp. Including the power

booster within the feedback loop of the driver ampliﬁer

results in a composite ampliﬁer with the accuracy of the

driver and the extended output voltage range and cur-

rent capability of the booster. The PB51 can also be

used without a driver in some applications, requiring

only an external current limit resistor to function prop-

erly.

• WIDE SUPPLY RANGE – ±15V to ±150V

• HIGH OUTPUT CURRENT –

1.5A Continuous (PB51),

2.0A Continuous (PB51A)

• VOLTAGE AND CURRENT GAIN

• HIGH SLEW –

50V/µs Minimum (PB51)

75V/µs Minimum (PB51A)

• PROGRAMMABLE OUTPUT CURRENT LIMIT

• HIGH POWER BANDWIDTH – 320 kHz Mini-

mum

• LOW QUIESCENT CURRENT – 12mA Typical

• EVALUATION KIT – EK29

The output stage utilizes complementary MOSFETs,

providing symmetrical output impedance and eliminat-

ing second breakdown limitations imposed by Bipolar

Transistors. Internal feedback and gainset resistors are

provided for a pin-strapable gain of 3. Additional gain

can be achieved with a single external resistor. Com-

pensation is not required for most driver/gain conﬁgura-

tions, but can be accomplished with a single external

capacitor. Enormous ﬂexibility is provided through the

choice of driver ampliﬁer, current limit, supply voltage,

voltage gain, and compensation.

APPLICATIONS

• HIGH VOLTAGE INSTRUMENTATION

• ELECTROSTATIC TRANSDUCERS &

DEFLECTION

• PROGRAMMABLE POWER SUPPLIES

UP TO 280V P-P

This hybrid circuit utilizes a beryllia (BeO) sub-

strate, thick ﬁlm resistors, ceramic capaci-

tors and semiconductor chips to maximize reli-

ability, minimize size and give top performance.

Ultrasonically bonded aluminum wires provide reliable

interconnections at all operating temperatures. The 12-

pin Power SIP package is electrically isolated.
