• Quasi−Resonant with Valley Switching Operation
• High Efficiency Operation
• Maximum Frequency Clamp (No Clamp, 80, 110 and 140 kHz)
• Flexible Design Options
• Frequency Jittering
• Improved EMI Signature
• LFF and BO Feature on a Dedicated Pin
• Enables Robust Designs
• Dual Frozen Peak Current
• Optimize Light Load Efficiency and Stand−by Performance
• Constant Voltage Primary−Side Regulation

• AEC-Qualifiied

应用 Application

• HEV & EV Vehicles
• OBC & Traction Inverters Auxiliary Power
• HV to LV DC/DC Converters Auxiliary Power

简介

NCV1362属于集成电路（IC）的ACDC转换器离线开关。由制造生产的NCV1362AC 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。
