NCP12601中文资料Multi-Mode PWM Controller for AC-DC Power Supplies and USB Power Delivery数据手册ONSEMI规格书

描述 Description

The NCP12601 is a multi-mode controller which implements valley switching mode with valley lockout for improved efficiency and noise-free operation. In high power conditions, the part operates in continuous conduction mode (CCM). As the load decreases, the converter enters discontinuous conduction mode (DCM) and skip mode in light or no load conditions. The NCP12601 PWM controller is optimized for USB PD applications with the integration of high-voltage start-up, X2 discharge, auto-tuning OCP, and low loss dynamic self-supply, thus reducing BOM cost.

简介

NCP12601属于集成电路（IC）的ACDC转换器离线开关。由制造生产的NCP12601AC DC 转换器，离线开关该系列是元器件级控制产品，用于构建将交流市电转换为直流电（通常电压大幅降低）的设备。集成和未集成系统主要开关元件的器件均包括在内。由于高输入输出电压比，以及此类系统中通常需要隔离，这些器件通常与外部变压器配合使用。尽管通常使用定制变压器来实现此用途，但也有许多专门用于此用途的库存产品，请参见“开关转换器，SMPS 变压器”标题。
