Allowable power consumption
It measures the ability of equipment to dissipate heat from the power supply equipment connection point to the final radiator and the surrounding environment. Therefore, the power distribution depends on the ambient temperature and the thermal resistance on various interfaces between the tube core junction and the ambient air. The maximum allowable power distribution of the equipment in a given package can be calculated using equations. The actual power distributed in the equipment can be expressed by equations: the voltage drop at both ends of the device and the continuous current adaptability of the device. These two equations are used to determine the The best operating conditions of the equipment in use. In applications with low power consumption and/or excellent package thermal resistance, the maximum ambient temperature may increase. In applications with high power dissipation and/or poor package thermal resistance, the maximum ambient temperature may have to be reduced. The maximum ambient temperature depends on the maximum allowable power distribution of the device package in the application (=°) and the device in the application
The environmental thermal resistance of the package must be reduced
This can be achieved by reducing within the – period as long as it meets the minimum or by reducing the period or by some combination of the two. External calculators are the same as most regulators and need external calculators to maintain the stability of regulators and are specially designed for portable applications that require minimum board size and minimum components. These supervisors must be selected correctly to obtain good performance. Input stability of calculators requires input calculations It is recommended to connect a μ The controller must be located no more than the pin and returned to a clean analog grounding input. Any high-quality ceramic tantalum or film capacitor can be used. Important: To ensure stable operation, good design practices must be used to minimize the grounding impedance and maintain the input inductance
