NCP1340
feature
, the NCP1340 can enable no-load power consumption below 30 m W.
The NCP1340 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 NCP1340 enters quiet-skip mode to manage the power delivery while minimizing acoustic noise.
To help ensure converter ruggedness, the NCP1340 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.
If transient load capability is desired, the NCP1341 offers the same performance and features with the addition of power excursion mode (PEM).
