Basic Calculation of a Buck Converter's Power Stage (Rev. B)
www.ti.comInductor Ripple Current: !I = L - ´ f ´ Inductor Selection www.ti.com η= efficiency of the converter, e.g., estimated 90% The efficiency is added to the duty cycle calculation, because the converter also has to deliver the energy dissipated. This calculation gives a more realistic duty cycle than just the formula without the efficiency factor.
Power Loss Calculation With CSI Consideration for ...
www.ti.comThe synchronous buck converter is a widely used topology in low-voltage, high-current applications. Low-power loss and highly efficient synchronous buck converters are in great demand for advanced microprocessors of the future. Good understanding of power losses in a synchronous buck converter is critical for improving converter performance.
