Up to 10A Output

The AAT1185 single output step-down controller supports a wide 6V to 24V input range. Output voltage is adjustable from 0.8 to 5.5V. Output current ranges from < 1A up to 10A. The controller provides high and low-side pins to drive external N-Channel power MOSFETs. Both drive pins are compatible with a wide range of external MOSFETs allowing designers to use the AAT1185 to develop control solutions for both low power and high power configurations.

The AAT1185's constant frequency voltage mode control allows designers to optimize performance across the entire output voltage and load range. A high 490 kHz switching frequency helps designers keep external component size small and efficiency high by supporting the use of a wide range of L/C filtering components. External compensation allows the designer to optimize transient response. Shutdown current is < style="font-style: italic;">Continued...
