AAT2687
PMIC Solution for 24V Systems with 2 High Performance Step-Down Converters
General Description
The AAT2687 provides two independently regulated DC outputs; consisting of a high voltage step-down
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
regulator with an input voltage range 6.
0 to 24V, providing up to 4.
5A output current.
490kHz fixed switching frequency allows small L/C filtering components.
Channel 1 utilizes voltage mode control configured for optimum performance across t...
