The AAT1130 SwitchReg™ is a member of AnalogicTech’s Total Power Management IC™ product family. The converter uses a predictive on-time, current-mode step-down control scheme that provides a fixed 2.5MHz switching frequency (under steady state conditions). It allows the control circuit to react nearly instantly in order to improve transient response and to enhance stability with the LC components as small as 1.0μH. The unique architectureimproves transient response while allowing tiny passive LC filter components. The high switching frequency (up to 2.5MHz) keeps output voltage ripple low.
