Adaptive Multi-Rail Power Platform B – AmP


Product Description

The AmP™ device is an FPGA based platform for creating a custom Power Management Integrated Circuit (PMIC). The AmP device is customized by adding available Power Components designs based on system requirements. AmP device customization is as easy as using WebAmp™ application software to produce a customized PMIC in a very short period of time. AmP devices can be used to power FPGAs, Processors, Microcontrollers, and ASICs by integrating multiple power rails into single chip designs. The AmP device input voltage range is 4.5V to 20V. The AmP device is targeted for wall-powered applications or 2S-4S Li-Ion battery packs. AmP devices have up to 4 additional integrated LDOs of which two are fixed output voltages (3.3V and 1.2V) and two are user programmable.
