CY8CKIT-035 PSoC® Power Management Expansion Board Kit

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 CreatorTM 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.

The Power Management Expansion Board Kit (EBK) supports:

Rapid fault detection capabilities for high-availability systems

Accurate and reliable power rail sequencing of both power-on and power-off for four different power converters

Voltage and current monitoring of four different power converters

Trimming for closed-loop control of the power converters

Margining of power converters for developmental test purposes

EEPROM based data logging capabilities

I2C/SMbus/PMbus host interface
