IC card examination pass IC卡准考证
All control circuits are integrated (including power MOS) in the IC except the output low-pass filter, two optional operation modes: PWM and PFM are available.
该IC集成了除输出低通滤波器的所有控制电路(包括功率MOS)，提供PWM和PF M两种模式供选择。
The low pass filters are preferably non-IC-low pass filters without active IC-elements.
该低通滤波器优选地是不具有有源ic元件的非ic低通滤波器。
