Introduction

ADP1882-1.0-EVALZ is a type of evaluation board which belongs to the category of DC/DC and AC/DC (Off-Line) SMPS (Switched Mode Power Supplies). It is developed by Analog Devices, Inc., a company specialized in Signal Processing, Data Converter and Power Management solutions. The board has a wide range of applications, including but not limited to embedded systems power, telecom power, portable device power, datacenter power, AC/DC conversion, and DC/DC conversion. In this article, the application fields and working principles of this board are discussed in details.

Application Fields

ADP1882-1.0-EVALZ can be broadly applied in three main fields, namely embedded systems, telecom power, and portable device power. In embedded systems, the evaluation board can be used to efficiently power connected devices such as microprocessors, sensors, and memories. Such applications typically require higher power density, integration, and improved thermal management. In telecom power applications, ADP1882-1.0-EVALZ can be used to provide more reliable and cost-effective power solutions for applications including central office and mobile base stations. Lastly, in portable device power applications, the evaluation board can be used to provide power to handheld and battery-powered devices such as cell phones, digital cameras, and medical devices.

Working Principles

The heart of the ADP1882-1.0-EVALZ board is its controller IC, the ADP1882 regulator. The ADP1882 is a current-mode control switch-mode regulator with a digitally adjustable output voltage ranging from 0.6V up to 1.8V and an output current limit of up to 8A. Furthermore, it integrates two analog voltage reference (AVREF), one low current threshold (LICT) and one high current threshold (HICT). Through the use of these AVREFs, the board’s output voltage is continuously adjustable using a single resistor to set the voltage for a given application. Additionally, the board features short-circuit and over-temperature protection for safe operation and enhanced reliability. The ADP1882-1.0-EVALZ evaluation board offers a versatile platform for testing and evaluating the ADP1882 regulator. The board features an adjustable output voltage and thermal protection, adjustable current limit protection, adjustable soft-start and synchronization to external clock, and an integrated frequency compensation network. The output voltage can be fine-tuned with a single resistor, and the current limit can be adjusted with a single digital potentiometer. Furthermore, the board features an onboard heatsink which ensures optimal thermal performance.

Conclusion

ADP1882-1.0-EVALZ is an evaluation board designed for testing and evaluating the ADP1882 regulator from Analog Devices, Inc. It can be broadly applied in embedded systems, telecom power, and portable device power applications. The board features an adjustable output voltage and adjustable current limit protection, adjustable soft-start and synchronization to external clock, and an integrated frequency compensation network. Additionally, it also features an onboard heatsink which ensures optimal thermal performance.
