NCP1256规格书详情
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.
Features
• Fixed−frequency 65−kHz or 100−kHz Current−mode Control
Operation
• Adjustable Over Power Protection (OPP) Circuit, Disabled at Low
Line
• Adjustable Brown Out Level
• Frequency Foldback down to 26 kHz and Skip−cycle in Light Load
Conditions
• Internally−fixed Slope Compensation Ramp
• Internally−fixed 4−ms Soft−start
• 70−ms Timer−based Auto−recovery Short−circuit Protection
• Frequency Jittering in Normal and Frequency Foldback Modes
• Double Hiccup Auto−recovery Short−circuit Protection
• Pre−short Ready for Latched OCP Option
• Latched/Auto−Recovery OVP Protection on Vcc
• Latched Inputs for Improved Robustness (OVP and OTP
implementations)
• Auto−Recovery ac Line OVP Protection (E Version)
• +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
NCP1256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NCP1256AC 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。
