      The Si9110/9111 are BiC/DMOS integrated circuits designed for use as high-performance switchmode controllers. A high-voltage DMOS input allows the controller to work over a wide range of input voltages (10- to 120-VDC). Current-mode PWM control circuitry is implemented in CMOS to reduce internal power consumption to less than 10 mW. A push-pull output driver provides high-speed switching for MOSPOWER devices large enough to supply 50 W of output power. When combined with an output MOSFET and transformer, the Si9110/9111 can be used to implement single-ended power converter topologies (i.e., flyback, forward, and cuk). The Si9110/9111 are available in both standard and lead (Pb)-free 14-pin plastic DIP and SOIC packages which are specified to operate over the industrial temperature range of −40 C to 85 C.

      The function and basic performance of the pressure reducing valve of the compressed air filter

      The filter, pressure reducing valve and lubricator together form a pneumatic triplet. The filter is mainly responsible for filtering the liquid water, oil and impurities in the compressed air, the pressure reducing valve is mainly responsible for controlling the system pressure, and the oil mist device is responsible for the oil lubrication of the back-end components.

      About the role of screw air compressor inverse proportional valve

      The inverse ratio valve is used in conjunction with the disc air intake control. When the system pressure increases due to the decrease in air consumption and reaches the set pressure of the inverse ratio valve, the inverse ratio valve acts and reduces the control air output.
