Basically, a power switch and a free-wheeling diode chop the dc input voltage to a rectangular waveform, then a low-pass LC filter sieves the high-frequency switching ripple and noise to get a almost pure dc voltage in the load terminal. Figure 1 shows a typical buck converter....
The calculated output voltage ripple during PSM mode = 33.2mVpp, so the measured ripple of 28.8mVpp matches the calculation result quite well.8 Practical example 2: RT5760A ACOT® Buck converter in 5V to 1.2V, 1A small size & low ripple application...
The operation principles of peak current control, V2 control, and enhanced- V2 control of buck converter in continuous conduction mode are reviewed and compared. By the use of weight factors of inductor current and output voltage, they are unified as constant-frequency peak-ripple-based (CF-PR)...
