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...
