AAT2688 Datasheet | Skyworks Solutions

DATA SHEET 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 munications 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 ponents. Channel 1 utilizes voltage mode control...
