NCP1250BP65G规格书详情
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.

NCP1250BP65G属于集成电路(IC) > AC DC 转换器,离线开关。安森美半导体公司制造生产的NCP1250BP65GAC 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。
