AAT2688
SystemPowerTM 4.
5A PMIC Solution for 12V Adapter Systems with 2-Output High Performance Step-Down Converters
General Description
The AAT2688 provides two independently regulated DC outputs: a high voltage synchronous step-down (Buck)
regulator and a low input voltage step-down low dropout (LDO)
regulator.
The PMIC is optimized for low cost 12V adapter inputs, making the device the ideal system-ona-chip power solution for consumer communications equipment.
Channel 1 is a step-down
regulator with an input voltage range of 6.
0V to 24V, providing up to 4.
5A output current.
490kHz fixed switching frequency allows small L/C filtering components.
Channel 1 utilizes voltag...
