NCP1239DD65R2G規(guī)格書詳情
NCP1239DD65R2G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NCP1239DD65R2GAC DC 轉(zhuǎn)換器,離線開關(guān)該系列是元器件級控制產(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現(xiàn)此用途,但也有許多專門用于此用途的庫存產(chǎn)品,請參見“開關(guān)轉(zhuǎn)換器,SMPS 變壓器”標(biāo)題。
The NCP1239 is a fixed-frequency current-mode controller
featuring a high-voltage start-up current source to provide a quick and
lossless power-on sequence. This function greatly simplifies the
design of the auxiliary supply and the VCC capacitor by activating the
internal start-up current source to supply the controller during start-up,
transients, latch, stand-by etc.
With a supply range up to 35 V, the controller hosts a jittered 65 or
100-kHz switching circuitry operated in peak current mode control.
When the power on the secondary side starts to decrease, the controller
automatically folds back its switching frequency down to minimum
level of 26 kHz. As the power further goes down, the part enters skip
cycle while limiting the peak current that insures excellent efficiency
in light load condition.
NCP1239 features a timer-based fault detection circuitry that
ensures a quasi-flat overload detection, independent of the input voltage.
