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.

NCP1060屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開(kāi)關(guān)。由制造生產(chǎn)的NCP1060AC DC 轉(zhuǎn)換器，離線開(kāi)關(guān)該系列是元器件級(jí)控制產(chǎn)品，用于構(gòu)建將交流市電轉(zhuǎn)換為直流電（通常電壓大幅降低）的設(shè)備。集成和未集成系統(tǒng)主要開(kāi)關(guān)元件的器件均包括在內(nèi)。由于高輸入輸出電壓比，以及此類系統(tǒng)中通常需要隔離，這些器件通常與外部變壓器配合使用。盡管通常使用定制變壓器來(lái)實(shí)現(xiàn)此用途，但也有許多專門(mén)用于此用途的庫(kù)存產(chǎn)品，請(qǐng)參見(jiàn)“開(kāi)關(guān)轉(zhuǎn)換器，SMPS 變壓器”標(biāo)題。
