Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPS

1. Overview

Evaluation boards (EVBs) for DC/DC and AC/DC switch-mode power supplies (SMPS) are specialized hardware platforms designed to demonstrate and validate the performance of power management integrated circuits (PMICs) and power modules. These boards enable engineers to assess critical parameters such as efficiency, thermal behavior, and dynamic response before integrating power solutions into end systems. With global demand for energy-efficient electronics growing, SMPS evaluation boards play a vital role in accelerating the development of power systems for applications ranging from consumer devices to industrial machinery.

2. Main Types and Functional Classification

Type	Functional Characteristics	Application Examples
Isolated AC/DC EVBs	Galvanic isolation, safety-certified designs	Medical power supplies, industrial SMPS
Non-Isolated DC/DC EVBs	Compact footprint, high-frequency operation	Point-of-load converters, telecom systems
Wide Bandgap (WBG) EVBs	GaN/SiC device evaluation, high-power density	Fast chargers, renewable energy systems
Digital Power EVBs	PMBus/PIC interfaces, programmable control	Server power, smart grid equipment

3. Structure and Components

Typical SMPS evaluation boards consist of: - PCB substrate with 2-10 layers for thermal management - Power stage components: MOSFETs, IGBTs, or wide-bandgap devices - Control circuitry: PWM controllers, gate drivers - Input/Output interfaces: Screw terminals, barrel connectors - Measurement points for voltage/current waveforms - Thermal vias and heatsinks for power dissipation

4. Key Technical Specifications

Parameter	Description	Importance
