The embedded network module series products of Yingchuang Company all have a streamlined ISA expansion bus, which usually includes several address buses, 8-bit data buses, read and write control li...[Details]

At present, products in the field of monitoring generally focus on the field level, that is, the client/server (C/S) model is adopted, the purpose of which is to ensure the stability and reliability o...[Details]

Designing with FPGA, DSP or microprocessor is a critical part of the design and also takes the most time. System-level designers can benefit greatly by focusing their main efforts on system desig...[Details]

Because we often design RF or low-frequency analog circuits, switching power supplies are rarely used in designs. However, in several cases, switching power supplies must be used to meet the perfor...[Details]

If a fixed clock is not used to initialize the on-time, but a detection circuit is used to effectively "sense" the first minimum or valley of the MOSFET (VDS) drain-source voltage and only start th...[Details]
