PRODUCT DATASHEET AAT2689 SystemPowerTM PMIC Solution for 12V Adapter Systems with 2-Output High Performance Step-Down Converters General Description The AAT2689 provides two independently regulated DC outputs, consisting of a high voltage step-down (Buck) regulator and a low input voltage low dropout (LDO) regulator. The PMIC is optimized for low cost 12V adapter inputs, making the device the ideal system-on-a-chip power solution for consumer communications equipment. Channel 1 is a step-down (Buck) regulator with an input voltage range of 6V to 24V providing up to 2500mA output current. 490kHz fixed switching frequency allows small L/C filtering components. Channel 1 utilizes voltage mode control configured for optimum performance across the entire output voltage and load range.
