NCP1339DDR2G規(guī)格書詳情

NCP1339DDR2G屬于集成電路(IC)的ACDC轉換器離線開關。由安森美半導體公司制造生產(chǎn)的NCP1339DDR2GAC DC 轉換器,離線開關該系列是元器件級控制產(chǎn)品,用于構建將交流市電轉換為直流電(通常電壓大幅降低)的設備。集成和未集成系統(tǒng)主要開關元件的器件均包括在內。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實現(xiàn)此用途,但也有許多專門用于此用途的庫存產(chǎn)品,請參見“開關轉換器,SMPS 變壓器”標題。

The NCP1339 is a highly integrated quasi?resonant flyback

controller capable of controlling rugged and high?performance

off?line power supplies as required by adapter applications. With an

integrated active X?cap discharge feature and power savings mode,

the NCP1339 can enable no?load power consumption below 10 mW

for 45 W notebook adapters.

The quasi?resonant current?mode flyback stage features a

proprietary valley?lockout circuitry, ensuring stable valley switching.

This system works down to the 6th valley and toggles to a frequency

foldback mode to eliminate switching losses. When the loop tends to

force below 25?kHz frequencies, the NCP1339 skips cycles to contain

the power delivery.

To help build rugged converters, the controller features several key

protective features: an internal brown?out, a non?dissipative Over Power

Protection for a constant maximum output current regardless of the

input voltage, a latched over?voltage protection through a dedicated pin.

Features

? High?voltage Current Source for Lossless Start?up Sequence

? X2 Capacitors Discharge Capability

? Power Savings Mode (PSM) for Extremely Low No?Load Power:

? Wide VCC Range from 10 V to 28 V

? Latching?off 28?V VCC Over?Voltage Protection

? Abnormal Overcurrent Fault Protection for Winding Short Circuit or Inductor Saturation Detection

? Integrated High?Voltage Startup Circuit with Brown?Out Detection

? Fault Input for Severe Fault Conditions, NTC Compatible for OTP

? Circuit Latching Off In Severe Fault Detection (OVP or OTP)

? Internal Temperature Shutdown

? Valley Switching Operation with Valley?Lockout for Noise?Free Operation

? Frequency Fold?back for Highest Performance in Standby Mode

? 25?kHz Clamp and Skip Mode

? Timer?Based Overload Protection (Latched or Auto?Recovery Options)

? Adjustable Overpower Protection

? 4?ms Soft?Start Timer

? ZCD Blanking Time to Ignore Leakage Ringing at Turn?Off:

3 us for C, D and E versions and 0.7 us for F, G, H, I and J versions

? Ready for High?Density QR design (F, G, H, I and J versions)

? These Devices are Pb?Free and are RoHS Compliant
