... ESR is as follows: V ripple Where maximum load current, and ESR. Compensation The AAT1346 employs current-mode control, thereby simplifying the control-loop compensation. When the AAT1346 operates with continuous inductor current (typically the case), a the loop-gain frequency response. To ensure stability, set the compensation for the below the lower of 1/10 the switching frequency (380kHz) ...
