NCP1219BD65R2G規(guī)格書(shū)詳情

NCP1219BD65R2G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NCP1219BD65R2GAC 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 NCP1219 represents a new, pin to pin compatible, generation

of the successful 7?pin current mode NCP12XX product series. The

controller allows for excellent standby power consumption by use of

its adjustable skip mode and integrated high voltage startup FET.

Internal frequency jittering, ramp compensation, timer?based fault

detection and a latch input make this controller an excellent

candidate for converters where ruggedness and component cost are

the key constraints.

The Dynamic Self Supply (DSS) drastically simplifies the

transformer design in avoiding the use of an auxiliary winding to

supply the NCP1219. This feature is particularly useful in

applications where the output voltage varies during operation (e.g.

battery chargers). Due to its high voltage technology, the IC can be

directly connected to the high voltage dc rail.

Features

? Fixed?Frequency Current?Mode Operation with Ramp

Compensation (65 kHz and 100 kHz Options)

? Dynamic Self Supply Eliminates the Need for an Auxiliary Winding

? Timer?Based Fault Protection for Improved Overload Detection

? Cycle Skip Reduces Input Power in Standby Mode

? Latch and Auto?Recovery Overload Protection Options

? Internal High Voltage Startup Circuit

? Accurate Current Limit Detector (±5)

? Adjustable Skip Level

? Latch Input for Easy Implementation of Overvoltage and

Overtemperature Protection

? Frequency Modulation for Softened EMI Signature

? 500 mA/800 mA Peak Source/Sink Current Drive Capability

? Pin to Pin Compatible with the Existing NCP12XX Series

? These Devices are Pb?Free and Halogen Free/BFR Free*

Typical Applications

? AC?DC Adapters for Notebooks, LCD Monitors

? Offline Battery Chargers

? Consumer Electronic Appliances STB, DVD, DVDR
