45V-5A 可调半桥直流到直流转换器 45V-5A 可调半桥直流到直流转换器 1 min Altium Designer Projects 简介 DC-DC降压转换器广泛应用于电子设备中。三种主要的非隔离型DC-DC转换器包括降压型（Buck）、升压型（Boost）和降升压型（Buck-Boost）。其中最常用的是降压型转换器。今天，我将向您介绍一种可调的半桥降压转换器，它能够处理6V至45V的输入电压，并提供高达5A的连续输出。您还可以调整输出电压，因此如果不需要电流调整，这个电路可以作为电源使用。 该设计采用了独立的PWM控制器和半桥驱动芯片，这使您能够通过最小的修改适应更高的电压和电流。开关频率设置在大约65KHz，但通过使用不同型号的半桥驱动芯片并重新计算开关电感，您可以达到更高的开关频率。 使用Altium Designer 23创建原理图和PCB，我收集了必要的元件信息，并通过Octopart网站快速生成了物料清单（BOM）。使用示波器、直流负载和台式万用表，我测试了电路的电压稳定性、输出噪声和负载阶跃响应。这是一件不错的硬件，让我们开始吧！ 规格 输入电压：6-45V DC 输出电压：3V至Vin-3 输出电流：5A - 连续（短期可达6 - 7A） 输出噪声（20MHz BWL）：5mVp-p（无负载），30mVp-p（5A） 输入功率：12V - 稳压 阅读文章
