### About "source/sink current on FB line" in IP2701 datasheet

To adjust a regulator's output voltage externally, you can inject or steal current to/from the FB node of the regulator using an external voltage source. See my answer here for how the mechanism works....

### How can tiny MOSFETs be rated for relatively high current?

Clearly some impractical conditions are being imposed, nicely described by Tim Williams. Here is an approach to estimating a more practical limit. They provide the Junction-to-Ambient thermal ...

### How can tiny MOSFETs be rated for relatively high current?

This is more of a "fusing" question, so I'll give a "fusing" answer: Fusing current is quite high for short durations. A 1mm copper wire (about 18 AWG) claims 83A for 10s, 250A ...

### How can tiny MOSFETs be rated for relatively high current?

They're being kind of dishonest. A bit, anyway. That 343A figure in Absolute Maximum Ratings is stated as 'Silicon Limited'. Look at the fine print in Note 1: From the data sheet. Got to watch out ...

### How can tiny MOSFETs be rated for relatively high current?

Package limit is 195A, and that is with the case held to 25°C, a practical impossibility in most situations. The lead length is short and we don't know what they are assuming for the termination of ...

### Working principle of AD8232 instrumentation amplifier

The output is the low pass filtered input. This can be seen from your equation. As long as the input spectrum is within the filter’s bandwidth, the output will be the input multiplied by the filter’s ...

### How to find current consumption of IC from datasheet?

which one do I need to choose for my power tree diagram? And what are all the different currents? Page 6 of the data sheet states what they are regarding the operational function of the device: - If ...

### Reverse Breakdown Voltage for a diode

Diodes have to work in both the forward biased and reverse biased regions. For example when used to rectify an AC waveform they are exposed to the full peak forward voltage and then in the other half ...

### I do not understand behavior of current in 74HC4066

All this really means is that the switch isn't quite bidirectional. To have it act as a switch where currents on both sides of the closed switch are same: Z must be no lower than 0.4V below Y when the ...

### I do not understand behavior of current in 74HC4066

Although the 4066 uses MOSFETs as its primary switching elements, it is constructed in such a way that parts of it behave like an NPN transistor with the collector tied to VDD, the emitter tied to the ...

### I do not understand behavior of current in 74HC4066

What it means is that there is an asymmetry between Z and Y and if the voltage drop across the switch (when the switch is 'on', only) is too large then some current will come from Vcc, which may be ...
