NCP1060数据手册集成电路（IC）的ACDC转换器离线开关规格书PDF

描述 Description

The NCP1060 integrate a fixed frequency current mode controller with a
700 V MOSFET. Available in a PDIP−7 and SOIC-10 package, the NCP1060 offer a high level of integration, including soft−start, frequency−jittering, short−circuit protection, skip−cycle,adjustablepeakcurrentsetpoint,rampcompensation,andaDynamic Self−Supply (eliminating the need for an auxiliary winding).Unlike other monolithic solutions, the NCP1060 is quiet by nature: during nominal
load operation, the part switches atone of the available frequencies (60or 100 kHz). When the output power demand diminishes, the IC automatically enters frequency foldback mode
and provides excellent efficiency at light loads. When the power demand reduces further, it enters into a skip mode to reduce the standby consumption down to a no load condition.Protection features include: a timer to detect an overload or a short−circuit event,
Overvoltage Protection with auto−recovery and AC input line voltage detection (A version).TheONproprietaryintegratedOverPowerProtection(OPP)letsyouharnessthe maximum delivered power without affectingyour standby performance simply via external resistors.The NCP1060/NCP1063 family can be seamlessly used both in non-isolated and in isolated topologies.

简介

NCP1060属于集成电路（IC）的ACDC转换器离线开关。由制造生产的NCP1060AC 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。
