aExternal resistor connection used to set the low current-limit threshold and the load detection current threshold. A resistor to ILIM_LO is optional; see Current-Limit Settings in DETAILED DESCRIPTION. 用于的外在电阻器连接设置低当前极限门限和装载侦查潮流门限。 一个电阻器对ILIM_LO是任意的; 看当前...
Fortunately, the new DC-DC converters provide a pin that allows adjustment of the current-limit threshold. By changing this threshold according to temperature, you can temperature-compensate the circuit's output-current limit. That task is readily accomplished with a thermistor as shown in Figure ...
PROTECTION CIRCUITRY: CURRENT LIMITING A 1.0 volt (typical) cycle-by-cycle current limit threshold is incorporated into the UCC3800 family. Note that the 100 nanosecond leading edge blank- ing pulse is applied to this current limiting circuitry. The blanking overrides the current limit comparator ...

A start-up circuit provides a start-up signal to initiate current flow to a load and also provides a foldback signal to set a current limit threshold under an over-load or short- circuit condition. A signal generator circuit operating on the regulated output voltage of the voltage regulator ...
A current limit can be added to a step-down converter by using a MAX4173H current-sense amplifier to inject current into the feedback network. D1 sharpens the threshold of current limit by converting the current sense feedback signal from linear to exponential. This current-limit circuit can...
A current limit circuit for preventing voltage overshoot in a driver circuit. A diode is coupled to the output terminal of the driver circuit. The diode's junction capacitance is utilized to reduce a current limit threshold in order to control the rate of change of the output voltage at the...
Using a comparator to compare the input voltage of the power switch to the output voltage of the power switch , an output signal is generated to control the current limit threshold. When the input voltage and output voltage has a large differential voltage, a lower current limit threshold ...
