Description

span id="lblDescription">

The AAT1185 is a single output step-down (Buck) regulator controller with an input range of 6V to 24V. The output range is adjustable from 0.8V to 5.5V.

The device AAT1185 provides high and low-side pins to drive external n-channel MOSFETs; allowing fully synchronous operation for maximum efficiency and performance. Alternately, the low-side MOSFET may be replaced with a Schottky rectifier. Both high and low-side drive pins are compatible with a wide range of external MOSFETs making the device the ideal control solution for low power and high power configurations.

Voltage mode control AAT1185 allows for optimum performance across the entire output voltage and load range. The 490kHz fixed switching frequency allows wide range of L/C filtering components, achieving smallest size and maximum efficiency. External compensation allows the designer to optimize the transient response.

The controller AAT1185 includes programmable over-current, integrated soft-start and over-temperature protection.

The AAT1185 is available in the Pb-free, 14-pin TSOPJW package. The rated operating temperature range is -40C to 85C.
