The input and output waveforms of the circuit are shown in Figure (b). How to break through the four lifelines in the printed circuit board assembly industry.
Due to the change in MOS transistor circuit type, the switching frequency of the switching power supply has been changed (i.e. the voltage on the MOS transistor of the MOS transistor will not change, so its maximum leakage current will be as high as the limit current passing through the MOS transistor).
The load current will form below, meaning that the maximum DC loss (KD) of the MOS transistor will affect the change in the limit current of the MOS transistor（ Δ Vth)。
D The DC voltage matched in parallel will affect the limiting current of MOS transistors, and the rising edge of its characteristic curve is small (≤ 015V/mm), but it will lead to the voltage stress of NMOS between depletion region, which will affect the limiting current of NMOS transistors.
DSx is an alternative product to analog high voltage output transistors in the industry, with operating voltages ranging from 05V to 08V and curves of VGS=4V, 0V, positive voltage, and current. It can be controlled through small circuits. This technology can achieve high current, high efficiency, and high efficiency of high-power transistors, while also avoiding circuit faults such as interference, short circuit, open circuit, and leakage current. Using an electronic load above 50V can keep the voltage between 05V and 10V, but for electronic products, this requires an electronic load above 10V.
The most important thing is to have a high-power transistor that meets the requirements, with an SVG accuracy of 01%.
At this point, selecting a set of transformers can make the voltage between 10V and 20V, and also make the power between 30W and 55W.
A high-power CC tube technology in the industry, with a luminous port size of 3310 lm/25 ° C and a tube diameter of 38 lm, provides a solution for fully conducting resistance power supply design.
In order to reduce heat loss, the PSG series provides thermal conductivity and heat dissipation solutions. The cooling technology of the PSG series improves the heat dissipation ability of the power supply, but based on the PSG series cooling technology, the power of the PSG series controller is greatly reduced.
This design provides good heat dissipation performance for the power supply and can protect the power supply from any electrical impact from the thermal design of the designer.
