SLIC的电源设计

系统包括语音服务与数据服务。这种系统使用用户线接口卡（ SLIC ）功能，以保持与原有设备的兼容性。在这些系统所需要的电压，因国家而异，取决于特定的应用程序。本文讨论了如何在使用MAX668升压控制器等系统所需的各种电压。分裂的反馈意见，以改善交叉调节。还介绍了一个例子是一个孤立的电源。

SLIC Power-Supply Design

Abstract: Integrated communication systems incorporate voice service with data service. Such systems use
subscriber-line interface card (SLIC) functions to maintain compatibility with legacy equipment. The voltages
required in these systems vary from country to country and depends on the particular application. This article
discusses how to derive various voltages required in such systems using the MAX668 boost controller. Split
feedback to improve cross-regulation is present
