NCP1256_V01規(guī)格書詳情

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

? 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
