Description: The AMC2576 series is a step-down switching regulator with all the required active functions. It is capable of driving 3A load with excellent line and load regulations. These devices are available in fixed output voltages of 3.3V, 5V, and an adjustable output version.
The AMC2576 series offers a high-efficiency replacement for popular three-terminal linear regulators. It requires only a minimum number of external components. Substantially, it reduces not only the area of board size but also the size of the heat sink. In some cases, no heat sink is required.
The ± 4％ tolerance on output voltage within specified input voltages and output load conditions is guaranteed. The oscillator frequency accuracy is within ±10％. External shutdown is included, featuring 70 A(typical) standby current. The output switch includes cycle-by-cycle current limitation, as well as thermal shutdown for full protection under fault conditions.

Description: 地线造成电磁干扰的主要原因是地线存在阻抗，当电流流过地线时，会在地线上产生电压，这就是地线噪声。在这个电压的驱动下，会产生地线环路电流，形成地环路干扰。当两个电路共用一段地线时，会形成公共阻抗耦合。 解决地环路干扰的方法有切断地环路，增加地环路的阻抗，使用平衡电路等。解决公共阻抗耦合的方法是减小公共地线部分的阻抗，或采用并联单点接地，彻底消除公共阻抗。-Ground caused by electromagnetic interference is mainly due to the existence of ground impedance, when the current flows through the ground, it will produce in the line voltage, which is ground noise. In this voltage-driven, will have a ground loop current, loop formation and disruption. When the two circuits share a section of ground wire, it will form a public-impedance coupling. Solution to loop interference method to have cut off the loop, increasing the loop impedance, the use of a balanced circuit. Solve the public-impedance coupling method is to reduce the public part of the impedance of ground wire, or parallel single-point grounding, the total elimination of public resistance.

Description: CRD5463PM Power Monitor
Reference Design and Software
The CRD5463PM demonstrates the CS5463 power measurement IC. It has an integrated AC-DC power supply,voltage and current sensors, and isolated UART/USB interface. Working with the GUI software, it provides accurate real-time measurements of line voltage, load current, line
frequency, active power, reactive power, pparent power,power factor, and temperature.
The CRD5463PM includes two power cords, a USB cable, and a plug adaptor. When used with a PC, the CRD5463PM immediately becomes a high-precision power meter. The UART interface communication protocol, GUI, and MCU software source codes are also available from Cirrus Logic.
The CRD5463PM is a useful design reference and evaluationtool for customers to develop power metering/monitoring systems that use the CS5463 IC.
