MAXREFDES130# Application Field and Working Principle

The MAXREFDES130# is a family of evaluation boards that allows users to test their own applications or circuits to determine its effectiveness. This board is offered in three distinct models: the MAXREFDES130#A, which is a power supply board; the MAXREFDES130#C, which tests circuit performance; and the MAXREFDES130#D, which is for evaluating signal conditioning circuits.The MAXREFDES130#A board includes a MOSFET-based switching converter architecture to provide step-down, step-up, or couple output modes. The working principle of the MAXREFDES130#A is based on a multi-channel selective analog-to-digital converter (ADC) with error detection, which converts input signals to digital data and then performs a frequency-to-digital conversion. The data obtained is used to control two high-frequency pulse waveforms in parallel, wherein two GaN power stages are used to regulate the output voltage accurately.The MAXREFDES130#C boards are based on a dual-channel time-interleaved ADC, which is designed to operate in a high-performance dynamic range, allowing users to test a wide variety of signal conditioning circuits such as bridge sensors, filter networks, and AC/DC-to-DC converters. This board utilizes a Multi-Level Modulation (MLM) technique, which features adjustable DC-link voltage levels and optimized PWM modulation for improved efficiency, thereby reducing load losses, THD, and transient speed.The MAXREFDES130#D board is an evaluation platform for AC/DC-to-DC converters and signal conditioning circuits. It is based on a quad-channel ADC, which converts analog signals into digital data that is then used to determine the switching control parameters of four independent groups of power switches, for modulation and zero-voltage switching (ZVS). The regulated output is then obtained via a stacked-inductor method or with a Liner Regulation (LR) technique.These MAXREFDES130# boards bring together the highest performance in terms of accuracy, power efficiency, transient response, and dynamic range. They are suitable for both product development and design verification, delivering the performance and reliability required to meet the most demanding applications.
