    MOSFET output current limited by Inductor Saturation current?

    The current will go to the bulk output capacitor bank with something like 5000uF-9000uF, then to high frequency ceramic caps and then to the CPU(processor). Some of the Intel processors, all of the i7 900 series have an 100A load step from idle to load. We overclock which means we take 2.8ghz...

    MOSFET output current limited by Inductor Saturation current?

    Wouldn't the MOSFET fry first? or what? which equation?

    MOSFET output current limited by Inductor Saturation current?

    I am just trying to analyze a circuit. I am not at that level yet for some of your questions. But I read that once saturation point is exceeded that the inductor losses inductance as the current rises significantly. Each phase, or driver with one pari of high-side and pair of low-side FET...

    MOSFET output current limited by Inductor Saturation current?

    it will damage the MOSFET, correct? Will there be any damage to the inductor or the bulk output capacitors?

    MOSFET output current limited by Inductor Saturation current?

    So the MOSFET's output current in a simple buck converter with a PWm a driver and a MOSFET and LC circuit. The Inductor's saturation or Irms current limits the MOSFET's current output, correct? I heard that if it exceeds saturation current that the MOSFETs could be damaged. is this true...

    Switching losses ESR and transient response

    ok its a mixed signal analog interleaved synchronous buck controller. So the feed back loop isn't controlled by PID or digital techniques. It uses current sensing across a voltage drop across a resister on every phase. I thought if switching frequency was increase overshoot and undershoot are...

    Switching losses ESR and transient response

    I am writing a review on a motherboard, and it has a "souped" up power supply for the cpu. I thought that switching losses from the MOSFETs hurt efficiency a lot and that is why we don't have motherboard power supplies that switch at 3mhz per channel. Plus the way computers are now you can't...

    Switching losses ESR and transient response

    I need someone to tell me if what I am saying is true or BS? Switching Frequency: Is simply defined as the frequency (amount of times) the same operation occurs, in our case the amount of times per second each phase is switched on. Duty Cycle: is thought of as the time the object is on...

    Switching frequency, phase multipliers, motherboards. Too many questions

    They power 130watt CPUs that operate at 1.3-1.9v, and that 130watt number is a thermal number, i have a wattage meter hookup to that 8pin 12v input from the computer's PSU, and I have pulled upto 200watts, that is with watercooling, when you use dry ice or liquid nitrogen the CPU will pull upto...

    Switching frequency, phase multipliers, motherboards. Too many questions

    Sorry :( so what shoudl i do? I don't want to make new threads just asking a specific question becuase i am scared i will get banned or deleted. A 24 phase VRm, is a 24 phase voltage regulator module. On a motherboard, it consists of the following: A pulse width modulator, basically outputs...

    no responses? not even one of my questions?

    Switching frequency, phase multipliers, motherboards. Too many questions

    Switching frequency, phase multipliers, motherboards. Too many questions! So i want to introduce myself, i went to Georgia Tech, and I got my BS in Biology, but ECE has always been kind of alike a hobby of mine. So i really like computers, but after interning in a engineering firm i decided to...
