开始

在许多应用中，次级电路的基准连接到与初级电路相同的基准 — 交流电源。在这种情况下，可以使用离线非隔离式辅助电源通过电感或低成本变压器（作为能量转移元件，使用简化的隔离，通过调节电源的占空比）提供稳定直流电压。

在输出电压需要为负时，可使用降压拓扑生成相对于公共端子和降压/升压的正输出。当需要更高的输出功率时，可以选择非隔离式反激转换器。

我们提供一系列集成式（实际上在单一封装中包含一个功率MOSFET、PWM控制器和保护电路）高压转换器（具有极低的待机功耗、高达800V和900V的击穿电压和众多保护特性），帮助实现效率最大化并提高电源可靠性。

此外，我们还提供全套硬件和软件评估与开发工具（包括参考设计），帮助产品快速上市。
