适用于医疗设备的小型低功率反激变换器

Tiny Low Power Flyback Converter for Medical

本文介绍了一种采用简单控制器和现有标准变压器组成的反激式解决方案。从成本的角度而言,该方案可说是隔离式方案的最佳选择。同时也实现了低功耗及耗用最少电路板空间的目标。

In this article we propose a flyback solution using a simple controller and a standard off-the-shelf transformer.As cost is always a concern,this is the optimum choice for the isolated solution.Due to the low power,the designer is also challenged to make his application as small as possible,similar to the non-isolated topologies.So in this proposal we aimed for a small PCB area as well.Even more challenging is the requirement for an operating temperature between 85℃and 105℃.This has also been met with the proposed solution.
