The ACOT® control scheme uses a virtual inductor current ramp generated inside the IC. This internal ramp signal replaces the ESR ramp normally provided by the output capacitor’s ESR. The ramp signal and other internal compensations are optimized for low-ESR ceramic output capacitors. Buck Operation Buck - Boost VIN VOUT LX1 LX2 S1 (A) S2 (B) S4 (D) S3 (C) BD AD Figure 1.
