The following is the general design sequence of switching power supply, which is helpful for beginners to master the design framework of switching power supply. A complete design process often involves repeated steps:

a: Select a converter circuit based on the input voltage range and output voltage. When the input voltage range is higher than the output voltage, select the BUCK converter; otherwise, select the boost converter. Sometimes it is also necessary to use a hybrid converter.

b: Select a control chip based on output power and physical size. Circuit complexity is often determined by output power. The greater the power, the larger the volume and the more complex the circuit structure. In this step, the amount of power usually affects the choice of switching frequency. Here, consider diode or synchronous rectification.

c: Select the inductor current ripple according to the needs of the output voltage ripple. Due to the interaction between capacitor ESR and ripple current, the size of the output current ripple will affect the selection of input and output capacitors.

d: Calculate the size of the inductor based on the input current ripple and average current.

e: Calculate the required current sampling resistor according to the specification of the control chip.

What is SMT in engineering?

Surface mount technology is a part of the electronic assembly that deals with the mounting of electronic components to the surface of a PCB. Electronic components mounted this way are called surface-mounted devices (SMD). SMT was developed to minimize manufacturing costs while making efficient use of board space.Qihe SMT company develops and produces all kinds of SMT equipment suitable for world wide market, including pnp machine,reflow oven,stencil printer,pcb handling machines,and other Smt pick and place machine products.

What is SMT in programming?

Offline Automated Programming vs Inline SMT Programming
Qihe pick and place machine can be programmed directly on the SMT equipment .
Or Coordinates can also be imported csv file through programming software.
Currently supported software such as protel,DXP,Altium Designer,Pads,Candes,proteus,DXP.
Inline SMT programming is a solution to consider for narrow segments of device programming requiring short programming times, with medium to high volume, for just one device type Smt pick and place machine .

WHAT IS SMT pick and place machine？

SMT (Surface Mounted Technology) is a comprehensive system engineering technology, which covers substrates, design, equipment, components, assembly processes, production accessories and management. When it comes to SMT pick and place machines, the automatic SMT production line requires automatic loading and unloading machine, automatic solder paste printing machine, placement machine, reflow soldering machine, AOI inspection equipment, conveyor,connecting table, etc. For these SMT assembly line equipment, Qihe SMT can offer you machines in prototype SMT line, small SMT production line, mass production SMT line at low SMT line cost.

WHAT IS SMT ASSEMBLY LINE？

With the development of technology, future electronic products will be lighter, smaller and thinner. Traditional assembly technology can no longer meet the requirements of high-precision and high-density assembly. A new type of PCB assembly technology-SMT (Surface Mount Technology) has emerged. SMT Assembly is the use of automated machines to assemble electronic components on the surface of the circuit board. Its density, high speed, standardization and other characteristics occupies an absolute advantage in the field of circuit assembly technology. In addition, SMT assembly has a wide range of uses.
