NCP1593A, NCP1593B
1 MHz, 3 A Synchronous
Buck Regulator
The NCP1593 is a fixed 1 MHz, high−output−current, synchronous
PWM converter that integrates a low−resistance, high−side P−channel
MOSFET and a low−side N−channel MOSFET. The NCP1593 utilizes
internally compensated current mode control to provide good transient
response, ease of implementation and excellent loop stability. It
regulates input voltages from 4.0 V to 5.5 V down to an output voltage
as low as 0.6 V and is able to supply up to 3 A of load current.
The NCP1593 includes an internally fixed switching frequency
(F
SW
), and an internal soft−start to limit inrush current. Other features
include cycle−by−cycle current limiting, 100% duty cycle operation,
short− circuit protection, power saving mode and thermal shutdown.

Limitations of FFT in Non-Stationary Signal Analysis
[size=4]FFT在非平稳信号分析中的局限性[/size] [size=4]很多论著上,几乎都提到了,FFT是一种线性的全局的处理方法,也就是说要么是时间域上观察信号,没有任何频率分辨率,要么在频率域上观察信号,没有任何的时间分辨率。从而论证FFT不适合处理非平稳信号。这个论断显然是正确的,而我的观点可能要在这个基础上再加上一点,如果信号本身是非平稳的,那么利用FFT得到的频谱处理结果会显然是...
