Designing DC/DC converters based on ZETA topology
www.ti.comThe ZETA converter also needs two inductors and a series capacitor, sometimes called a flying capacitor. ... steady-state peak current in the high-side inductor, as ... The power FET’s current rating will determine the ZETA converter’s maxi-
Voltage/Current Phase Angle
www.philsherrod.comFor resistance, and , so Power Factor = 1 For pure capacitance or inductance, and , so Power Factor = 0 In other words, inductors and capacitors don’t dissipate power – they store it. So power is dissipated only by current flowing through resistors. Power with resistance load Power with pure inductance or capacitance

www.ti.comcurrent limit of the device, ICLIM in Figure 1, and this could be much higher than the steady state value calculated above. If the inductor has saturated, and if the input DC voltage is higher than 40V the current could slew up at a rate so high that the controller may not be able to limit the current at all, leading to destruction of the switch.
LT8612 (Rev. B)
www.analog.com3µA Quiescent Current The LT®8612 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that consumes only 3µA of quiescent current. Top and bottom power switches are included with all necessary circuitry to minimize the need for external components. Low ripple Burst Mode operation enables high efficiency
Chapter 31 Alternating Current Circuits
www.austincc.eduAverage Power - Inductors Inductors don’t dissipate energy, they store energy. The voltage and the current are out of phase by 90 o. As we saw with Work, energy changed only when a portion of the force was in the direction of the displacement. In electrical circuits energy is dissipated only if a portion of the voltage is in phase with the ...
