The AAT1189 is a single-output step-down (Buck) DC-DC regulator from Skyworks Solutions, featuring an integrated high-side MOSFET. It is designed for input voltage ranges from 6V to 24V, making it suitable for consumer communications equipment powered by standard 12V AC/DC adapters.
This regulator provides up to 2.5A of output current and operates at a fixed switching frequency of 490kHz, which allows for the use of small L/C filtering components. The voltage mode control ensures optimal performance across various output voltages and load conditions. The controller includes programmable over-current protection, integrated soft-start, and over-temperature protection for enhanced reliability.
The AAT1189 is available in a low-profile, 16-pin TDFN34 package. It has a rated operating temperature range of -40°C to 85°C. Key features include adjustable output voltage from 1.5V to 5.5V, low shutdown current (<35 μA), and PWM fixed frequency for minimal noise.
Applications for this device include DSL and cable modems, notebook computers, satellite set-top boxes, and wireless LAN systems.
