Under the expansion of production, China’s power semiconductors will be in surplus?
As the core component of power conversion and circuit control, power semiconductors are widely used in automobile, consumer electronics, computer, network communication, industrial control and other scenes, of which the demand for automobiles accounts for the highest, nearly 40%. However, China’s power semiconductor industry started late and the localization rate is low. Coincided with the […]
Using ADI’s lt1083 regulator to realize a simple and affordable solution
When designing the power supply part of any circuit board, the most commonly used voltage regulators are 78xx, 79xx, LM317, lm337 or similar devices. Engineers know that these controllers are safe, reliable and easy to use, but their current is limited. If more current is needed, ADI’s lt1083 regulator can be used to realize a […]
How to determine the minimum radiator size required for MOSFET
1. Preface It is assumed that the total calculated power consumption of the power MOSFET in our design circuit is 10W. The maximum junction temperature of the device is 150 ℃. Considering the temperature difference between junction and shell, the actual shell temperature of MOSFET must be kept at or below 100 ° C in […]
