NCP1250ASN100T1G規(guī)格書(shū)詳情
NCP1250ASN100T1G屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開(kāi)關(guān)。由安森美半導(dǎo)體公司制造生產(chǎn)的NCP1250ASN100T1GAC 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。
The NCP1250 is a highly integrated PWM controller capable of
delivering a rugged and high performance offline power supply in a
tiny TSOP?6 or PDIP?8 package. With a supply range up to 28 V, the
controller hosts a jittered 65 kHz 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 a minimum level of 26 kHz. As
the power further goes down, the part enters skip cycle while limiting
the peak current.
Over Power Protection (OPP) is a difficult exercise especially when
no?load standby requirements drive the converter specifications. The
ON proprietary integrated OPP lets you harness the maximum
delivered power without affecting your standby performance simply
via two external resistors. An Over Voltage Protection input is also
combined on the same pin and protects the whole circuitry in case of
optocoupler failure or adverse open loop operation.
Finally, a timer?based short?circuit protection offers the best
protection scheme, letting you precisely select the protection trip point
irrespective of a loose coupling between the auxiliary and the power windings.
