Here is a list of upcoming Easter dates, calculated in Excel. The dates were calculated using the User Defined Function, CalculateEaster, shown in the United States Naval Observatory Algorithm section, further down on this page.Note: For actual dates of Easter 20 years in the past, for this...
Power Management Texas Instruments Incorporated IQ: What it is, what it isn't, and how to use it By Chris Glaser Applications Engineer Introduction A device's quiescent current, or IQ, is an important yet often misused parameter for low-power, energy-efficient designs. In many battery-powered...
To address this difference between the IQ and the no- load input current, the datasheets of some ICs have typical specifications for the no-load input current in the electri- calculated. Due to the high input current during the cal characteristics table. Others have graphs that show ...

The current ripple, shown as ΔIL in Figure 2, is calculated using ΔIL = (VIN× tON)/L. The average inductor current flows into the load, while the ripple current flows into the output capacitor.Figure 3. Boost regulator integrates oscillator, PWM control loop, and switching FETs....
(CCM), the inductor current never drops to zero; when operating indiscontinuous conduction mode(DCM), the inductor current can drop to zero. Thecurrent ripple, shown as ΔILin Figure 2, is calculated using ΔIL= (VIN×tON)/L. The average inductor current flows into the load, while the ...
