Functional Description
AAT1130 high performance 500mA 2.5MHz (maximum switching frequency during steady-state operation) monolithic step-down converter. minimizes external component size, enabling tiny 0603 inductor that only tall, optimizes efficiency over complete load range. Apart from small bypass input capacitor, only small filter required output. Typically, inductor 4.7F ceramic capacitor recommended <1.2V output voltage applications (see table values). Only three external power components (CIN, COUT, required, fixed output voltage options. Output voltage programmed with external feedback resistors, ranging from 0.6V 1.8V. additional feed-forward capacitor also added external feedback provide improved transient response (see Figure input voltage range 2.7V 5.5V. converter efficiency been optimized load conditions, ranging from load 500mA. internal error comparator incorporated compensation provide excellent transient response, load, line

Control Loop
AAT1130 uses current-mode control scheme that allows operate very high switching frequencies. current-mode control scheme operates with fixed on-time given input voltage. on-time varies inversely proportional input voltage proportional output voltage giving regulator fixed switching frequency when steady-state. This allows very small external inductor capacitor. small size coupled with quiescent current automatic transition variable switching frequency mode makes ideal small battery operated applications.

This added benefit reducing switching transition losses improving efficiency light loads.

Example: Given that VOUT 1.2V, then COUT 4.24F, therefore 4.7F capacitor suitable. unique control method, "inside" current control loop does have inherent instability that plagues most fixed frequency current-mode DC-DC regulators.
Stability
AAT1130 requires additional compensation components guarantee stability. only requirement stability choose appropriate output capacitor. Current-mode control simplifies compensation controlling inductor current regulate output voltage. This approximates single pole response loop gain even though complex pole pair exists filter. Therefore crossover frequency approximated loop gain multiplied single pole. AAT1130 loop gain function current sense resistor determined equation:
Soft-Start
When AAT1130 enabled, enters soft-start mode. this mode, output voltage slowly rises over 150s allowing output capacitor charge without drawing excessive input current. This feature prevents overstressing battery other input power source.
Current Limit
AAT1130 includes cycle-by-cycle current limit prevent damage itself external circuitry. current limit valley current limit using n-channel synchronous rectifier measure current. synchronous rectifier current above valley current limit, AAT1130 holds synchronous rectifier until current below limit. This allows AAT1130 control current current limit even with hard shorted output.
