Description

the normalized voltage, defined by | V o | = V o V i {\displaystyle \left|V_{\text{o}}\right|={\frac {V_{\text{o}}}{V_{\text{i}}}}} . Find some of the lowest I Q products in our buck converter portfolio below including the TPS62x family of low-power converters with DCS control technology and the world's lowest I Q switching regulator, the TPS62840.

DC/DC buck switching regulators with ultra-low-standby quiescent current increase light-load efficiency and extend battery life in portable and battery-operated applications. Switching converters (such as buck converters) provide much greater power efficiency as DC-to-DC converters than linear regulators, which are simpler circuits that dissipate power as heat, but do not step up output current. This section may be written in a style that is too abstract to be readily understandable by general audiences. If the switch is opened while the current is still changing, then there will always be a voltage drop across the inductor, so the net voltage at the load will always be less than the input voltage source.

Several factors contribute to this including, but not limited to, switching frequency, output capacitance, inductor, load and any current limiting features of the control circuitry. So, in steady state operation of the converter, this means that | I o | {\displaystyle \scriptstyle \left|I_{o}\right|} equals 0 for no output current, and 1 for the maximum current the converter can deliver.

In either mode, only one switch controls the duty cycle, another is for commutation and must be operated inversely to the former one, and the remaining two switches are in a fixed position. The "increase" in average current makes up for the reduction in voltage, and ideally preserves the power provided to the load. To even out voltage spikes from the switching between on-state and off-state, a capacitor is used on the output side.

Limit between continuous and discontinuous modes [ edit ] Fig 5: Evolution of the normalized output voltage with the normalized output current in a buck–boost converter. Output voltage ripple is one of the disadvantages of a switching power supply, and can also be a measure of its quality. the output voltage can vary continuously from 0 to − ∞ {\displaystyle \scriptstyle -\infty } (for an ideal converter). the current at the limit between continuous and discontinuous mode is I o lim = V i T 2 L D ( 1 − D ) = I o lim 2 | I o | D ( 1 − D ) {\displaystyle \scriptstyle I_{o_{\text{lim}}}={\frac {V_{i}\,T}{2L}}D\left(1-D\right)={\frac {I_{o_{\text{lim}}}}{2\left|I_{o}\right|}}D\left(1-D\right)} . But with the industry's best noise and ripple performance, TPS62912 and TPS62913 allow you to remove that low-noise LDO in most applications, saving PCB area and overall cost while improving system efficiency.

This assumption is acceptable because an inductor is made of one long wound piece of wire, so it is likely to exhibit a non-negligible parasitic resistance ( R L). PSpice® for TI is a design and simulation environment that helps evaluate functionality of analog circuits. Evolution of the output voltage of a buck converter with the duty cycle when the parasitic resistance of the inductor increases.However, since the inductor doesn't allow rapid current change, it will initially keep the current low by dropping most of the voltage provided by the source.
