Low Cost Open Frame Package, High Current 10A, 100V Power Amplifier

The MP39 is a cost-effective high voltage MOSFET power operational ampli,er constructed with surface mount com- ponents on a thermally conductive but electrically isolated substrate. While the cost is low the MP39 offers many of the same features and performance speci,cations found in much more expensive hybrid power ampli,ers. The metal substrate allows the MP39 to dissipate power up to 125 watts and its power supply voltages CAN range up to +/- 50 Volts (100V total). Optional boost voltage inputs allow the small signal portion of the ampli,er to operate at higher supply voltages than the high current output stage. The ampli,er is then biased to achieve close linear swings to the supply rails at high current for extra ef,cient operation. External compensation tailors performance to the user needs. A four-wire sense technique allows current limiting without the need to consider internal or external mili-ohm parasitic resistance in the output line. An Iq pin is available which CAN be used to shut off the quiescent current in the output stage. The output stage then operates class C and lowers quiescent power dissipation. This is useful in applications where output crossover distortion is not important. By Cirrus Logic, Inc.
