SwitchRegTM
General Description
The AAT1189 is a single output step-down (Buck) DC output regulator with an integrated high side
MOSFET.
The input range is 6V to 24V making it the ideal power IC solution for consumer communications equipment operating from a low cost AC/DC adapter with 12V output.
The step-down regulator provides up to 2.
5A output current in a small package.
490kHz fixed switching frequency allows small L/C filtering components.
Voltage mode control allows for optimum performance across the entire output
voltage and load range.
The controller includes programmable over-current, integrated soft-start and over-temperature protection.
The AAT1189 is available in the Pb-free, lo...
