NCP1341規(guī)格書詳情
The NCP1341 is a highly integrated quasi?resonant flyback
controller suitable for designing high?performance off?line power
converters. With an integrated active X2 capacitor discharge feature,
the NCP1341 can enable no?load power consumption below 30 mW.
The NCP1341 features a proprietary valley?lockout circuitry,
ensuring stable valley switching. This system works down to the 6th
valley and transitions to frequency foldback mode to reduce switching
losses. As the load decreases further, the NCP1341 enters quiet?skip
mode to manage the power delivery while minimizing acoustic noise.
The NCP1341 integrates power excursion mode (PEM) to minimize
transformer size in designs requiring high transient load capability. If
transient load capability is not desired, the NCP1340 offers the same
performance and features without PEM.
To help ensure converter ruggedness, the NCP1341 implements
several key protective features such as internal brownout detection, a
non?dissipative Over Power Protection (OPP) for constant maximum
output power regardless of input voltage, a latched overvoltage and
NTC?ready overtemperature protection through a dedicated pin, and
line removal detection to safely discharge the X2 capacitors when the
ac line is removed.
Features
? Integrated High?Voltage Startup Circuit with Brownout Detection
? Integrated X2 Capacitor Discharge Capability
? Wide VCC Range from 9 V to 28 V
? 28 V VCC Overvoltage Protection
? Abnormal Overcurrent Fault Protection for Winding Short Circuit or
Saturation Detection
? Internal Temperature Shutdown
? Valley Switching Operation with Valley?Lockout for Noise?Free
Operation
? Frequency Foldback with 25 kHz Minimum Frequency Clamp for
Increased Efficiency at Light Loads
? Skip Mode with Quiet?Skip Technology for Highest Performance
During Light Loads
? Minimized Current Consumption for No Load Power Below 30 mW
? Frequency Jittering for Reduced EMI Signature
? Latching or Auto?Recovery Timer?Based Overload Protection
? Adjustable Overpower Protection (OPP)
? Fixed or Adjustable Maximum Frequency Clamp
? Fault Pin for Severe Fault Conditions, NTC Compatible for OTP
(9?Pin Version Only)
? 4 ms Soft?Start Timer
NCP1341屬于集成電路(IC) > AC DC 轉換器,離線開關。安森美半導體公司制造生產的NCP1341AC DC 轉換器,離線開關該系列是元器件級控制產品,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品,請參見“開關轉換器,SMPS 變壓器”標題。
