the resistance increases as the temperature rises. The NTC resistor is connected in series into the input terminal of the power supply. When the power is on, the temperature of the resistor is low, so there is a certain resistance value, which can restrain the surge of power on. When the...
A current limiting circuit is connected between one of the rectifier output terminals and an electrode of the first capacitor in order to limit the inrush current occurring when the power supply is switched on. The current limiting circuit includes a parallel connection of a first resistor and a...
Customer measured that tps63000 has big inrush current during startup that would pull Vin a little lower. Startup test condition, Input is 5V, output is 5.5V/no load, EN is enabled by PG of upstream LM73100. The input power supply might have limited inrush ...
The adjustable rise time control of the device greatly reduces inrush current for a wide variety of bulk load capacitances, thereby reducing or eliminating power supply droop. 但是这个应该是说的是芯片正常启动情况下,而不是热插拔。如果你有热插拔需求应该选择热插拔功能的芯片, 你可以看TPS24710系列和...
