Applications—including printers, data-storage equipment, audio amplifiers and motor drivers—usually require power supplies that deliver high peak-to-nominal load ratios. The HFC0300 is a variable off-time controller optimized for these applications. This application note introduces the operating principles and features of HFC0300 for delivering peak load, and outlines an optimized peak-power design method that lowers power loss and minimizes transformer size. Finally, this application note provides a detailed step-by-step design example with peak load profile, which includes both theoretical calculations and experimental verification.
应用（包括打印机，数据存储设备，音频放大器和电动机驱动器）通常需要电源，以提供较高的峰峰值负载比。 HFC0300是针对这些应用而优化的可变停机时间控制器。 本应用笔记介绍了HFC0300用于提供峰值负载的工作原理和功能，并概述了一种优化的峰值功率设计方法，该方法可降低功耗并减小变压器尺寸。 最后，本应用笔记提供了一个详细的分步设计示例，其中包含了峰值负载曲线，其中包括理论计算和实验验证。
