Operation
The RT6160A is a high-efficiency, single inductor,
Advanced Constant On-Time ACOT® mode control
mechanism to achieve fast-transient response and
good stability with low-ESR ceramic capacitors. 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.
