Class D Audio


Monolithic Power Systems (MPS) is a leading fabless manufacturer of high-performance analog and mixed-signal semiconductors. MPS’ proprietary BCD Plus™ process technology is key to its competitive advantage. Many conventional analog technologies are handicapped by an inability to support the integration of power devices at high power levels. This results in unacceptably large semiconductors and/or significant levels of power loss. MPS’ BCD Plus process technology resolves each of these issues. Implemented at standard CMOS foundries, this unique process integrates BiCMOS signal transistors with a highly efficient DMOS power transistor. This allows MPS to design and deliver smaller, single-chip power management ICs that are highly efficient and accurate. In addition, MPS’ single process technology simplifies the design process, and is applicable across a wide range of analog applications. The result is higher productivity and significant cost advantages for any MPS customer.
