1 Inroducion Oupu Volage ipple in Sep-Down and Sep-Up Swiching egulaors Oupu volage ripple is always an imporan performance parameer wih DC-DC converers. For inducor-based swiching regulaors, several key facors can affec his imporan parameer, including swiching frequency, duy cycle, and oupu capacior value. Sep-down and sep-up swiching regulaors have differen circui opologies, so some facors ha affec he oupu volage ripple for sep-down DC-DC converers will no affec oupu volage ripple for sep-up DC-DC converers. This applicaion noe analyzes facors affecing oupu volage ripple based on he derived oupu volage ripple equaions for sep-down and sep-up DC-DC converer opologies in CCM. This documen can help provide insigh in undersanding oupu volage ripple. Sep-Down Converer Oupu ipple IN Sep-Down IC Q PMOS Conrol Circui Q NMOS SW FB L I L C + GND - Figure : Sep-Down DC-DC Converer. To derive he sep-down DC-DC converer oupu volage ripple equaion, coninuous conducion mode (CCM) operaion is assumed. The oupu volage includes he DC componen and AC componen. is produced by he inducor curren I L flowing hrough he load ( in Figure ) and oupu capacior (C in Figure ). In a well designed converer, he oupu capacior will provide a very low impedance o ground wih respec o he load a he sep-down DC-DC regulaor swiching frequency in order o filer he inducor AC ripple curren (ΔI L ). Hence almos all of he inducor AC ripple curren will flow hrough he oupu capacior, C in Figure. Inducor curren: il = IL + il Oupu volage: v O = + v O Using he circui in Figure, where he Q and Q ransisors are alernaively urned on/off, he following inducor curren componens (DC and AC) can be derived: Inducor curren DC componen: I L = I O = Inducor curren AC componen: i = - L L = L ( - ) Where D = duy cycle D = and T = swiching period.

Figure illusraes he ypical oupu capacior volage ripple waveform resuling from he inducor AC ripple curren flowing hrough he oupu capacior. Using he blue secion, or area under he waveform, of he oupu capacior curren (i C ) waveform in Figure, he oupu volage ripple equaion can be derived: v = i C 8 f C = f 8 f L C ( - D) W Q close Q open Q open Q close T i L IO i L (+D)T T i C (+D)T T i C = i L v O v O (+D)T T Figure : Typical Waveforms of a Sep-Down Converer.

(c) Figure : The Effec of Four Parameers [f, D, L, C] on Sep-Down Converer Oupu Volage ipple. From Figure, he following is observed: Swiching frequencies beween MHz ~ MHz resul in mv or less oupu volage ripple for oupu capacior values of 4.7µF ~ µf and inducor values of.4μh ~ 6.8µH wihou high swiching losses. As he duy cycle is increased, oupu volage ripple is decreased. In oher words, duy cycle is inversely proporional o oupu volage ripple. As he inducor value is increased, oupu volage ripple is decreased. In oher words, inducor value is inversely proporional o oupu volage ripple.
