General Description
The AAT1130 SwitchReg™ is a member of AnalogicTech’s Total Power Management IC™ product family. It is a fixed-frequency (during steady-state operation), current-mode step-down converter. The unique architecture improves transient response while allowing tiny passive LC filter components. The high switching frequency (up to 2.5MHz) keeps output voltage ripple low.
