Lattice LPTM10-12107混合信号平台管理方案 - 模拟电子技术 - 电子工程网

The Platform Manager product family represents the third-generation of mixed-signal devices available from Lattice. Programmable Platform Manager devices simplify board management design significantly by integrating programmable analog and logic to support many common functions, such as power management, digital housekeeping and glue logic. By integrating these support functions, Platform Manager devices not only reduce the cost of these functions compared to traditional approaches, but also improve system reliability and provide a high degree of design flexibility that minimizes the risk of circuit board re-spins.

Using the preloaded Board Digital Management design provided with the development kit, you can test within minutes power management functions such as power supply hot swap control, redundant supply selection and payload power management. Digital management support functions include reset distribution, system interfacing, power-on configuration and fault monitoring and logging. The kit also demonstrates enhanced power management features such as power supply closed loop trimming and margining. Power for the board comes from a 12VDC wall plug supply.

This user’s guide describes how to start using the Platform Manager Development Kit, an easy-to-use system for evaluating and designing with the Platform Manager mixed-signal device. The kit serves as a development test environment to build designs for power supply man agement functions such as sequencing, power supply fault logging, trimming, reset generation, high-side MOSFET drive and user logic I/O expansion in an FPGA.
