NCP1256規(guī)格書詳情
NCP1256屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)。由安森美半導(dǎo)體公司制造生產(chǎn)的NCP1256AC DC 轉(zhuǎn)換器，離線開關(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實(shí)現(xiàn)此用途，但也有許多專門用于此用途的庫存產(chǎn)品，請(qǐng)參見“開關(guān)轉(zhuǎn)換器，SMPS 變壓器”標(biāo)題。
The NCP1256 includes everything to build cost?effective switch
mode power supplies ranging from a few watts up to several tens of
watts. Housed in a tiny TSOP?6 package, the part can be supplied up
to 30 V. It hosts a jittered 65 or 100?kHz switching circuitry operated
in peak current mode control. When the power in the secondary side
starts decreasing, the controller automatically folds back its switching
frequency down to a minimum level of 26 kHz. As the power further
goes down, the part enters skip cycle while freezing the peak current.
NCP1256 comes with several protection features such as a
timer?based auto?recovery short circuit protection, lossless OPP, and
an easily adjustable Brown Out (BO) pin. Two inputs are provided to
latch off the part in a practical way, for instance with OVP and OTP
events. Several options exists to chose latch or auto?recovery for these events.

? +500 mA/ ?500 mA Source/Sink Drive Capability
? EPS 2.0 Compliant
? These are Pb?Free Devices
Typical Applications
? Ac?dc Adapters for Portable Devices, Computers, Tablets etc.
? Auxiliary Power Supplies
