WebFigure 1. Buck Converter Power Stage 1.1 Necessary Parameters of the Power Stage The following four parameters are needed to calculate the power stage: 1. Input voltage range: VIN(min) and VIN(max) 2. Nominal output voltage: VOUT 3. Maximum output current: IOUT(max) 4. Integrated circuit used to build the buck converter. WebIt shows that the output current is less than the input current. Hence the buck booster is a step up mode. Vin < Vout and Iin > Iout In the step down mode the input voltage is greater than the output voltage (Vin > Vout). It follows that the output current is greater the input current. Hence the buck boost converter is a step down mode.

WebThe shape of the current flowing in the inductor is similar to Figure 6. Figure 6. Buck Regulator Inductor Current As explained, the current through the inductor ramps up when the switch is on, and ramps down when the switch is off. The DC load current from the regulated output is the average value of the inductor current. WebThe Boost converter inductor current does not continuously flow to the load unlike that of the Buck converter. During the switch ‘on’ period the inductor current flows to ground and the load current is supplied from the output capacitor. The output capacitor therefore must have sufficient energy storage capability and ripple current rat-
