Part Number: PB50
Function: Power Booster Amplifier
Manufacturer: APEX MICROTECHNOLOGY CORPORATION
The PB50 is a high voltage, high current amplifier designed 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 current capability of the booster.
The PB50 can also be used without a driver in some applications, requiring only an external current limit resistor to function properly. The output stage utilizes complementary MOSFETs, providing symmetrical output impedance and eliminating secondary breakdown limitations imposed by Bipolar Junction Transistors. Internal feedback and gainset resistors are provided for a pin-strappable gain of 3. Additional gain can be achieved with a single external resistor. Compensation is not required for most driver/gain configurations, but can be accomplished with a single external capacitor. Although the booster can be configured quite simply, enormous flexibility is provided through the choice of driver amplifier, current limit, supply voltage, voltage gain, and compensation.
A power booster amplifier is a type of electronic device used to amplify the power or voltage of an input signal. Unlike regular amplifiers that focus on amplifying the signal’s voltage or current level to increase its amplitude, a power booster amplifier is specifically designed to provide higher output power levels.
In many cases, regular amplifiers are not capable of providing enough power to drive high-power loads such as loudspeakers, high-power transmitters, or other devices that require significant power levels. Power booster amplifiers are employed in these scenarios to boost the signal’s power and provide the necessary energy to drive such loads.
