Introduction to the PME EBK
In general terms, power management or power supervision is a combination of sequencing,
monitoring and control of multiple regulators and/or point-of-load DC power converters in a
system. Typical solutions for power management include multiple devices such as CPLDs,
mixed-signal ASICs and/or limited-functionality and inflexible discrete devices.
Power
management solutions require: (1) rapid fault detection capabilities for high-availability systems of
the power converters in the system; (2) accurate and reliable power rail sequencing of the power
converters during power-on and power-off events; (3) voltage and current measurement of the
power converters to optimize power consumption and/or for data logging; and, (4) closed-loop
control of the power converters through trimming and, for development and manufacturing test
purposes, margining of voltage rails in the system.
The PSoC Power Management Expansion Board Kit (PME EBK) is part of the PSoC development
kit ecosystem and is designed to work with the CY8CKIT-001 PSoC Development Kit (DVK) and
the CY8CKIT-030 PSoC 3 Development Kit (DVK). It enables you to evaluate the system power
management functions and capabilities of PSoC 3 devices. You can evaluate the example projects
described in this guide or design and customize your own system power management solution using
components in Cypress's PSoC Creator
TM
software (included in this kit) or by altering example
projects provided with this kit.
The PSoC Power Management Expansion Board Kit (PME EBK) is used with the PSoC family of
devices and is specifically designed and packaged for use with the PSoC 3 device family. PSoC 3 is
a programmable system-on-chip platform that combines precision analog and digital logic with a
high performance, single-cycle, 67MHz 8051 processor. With the flexibility of the PSoC
architecture, you can easily create your own custom power management solution on chip with the
exact functionality you need, in the way you want it—no more, no less.
