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.
Channel 2 is a low-dropout (LDO) regulator providing up to 600mA output current. The device provides extremely low output noise, low quiescent current and excellent transient response.
The AAT2689 controller includes integrated cycle-by-cycle over-current protection, soft-start and over-temperature disable features. Independent input and enable pins provide maximum design flexibility.
The AAT2689 is available in the Pb-free 3x4mm 16-pin TDFN package. The rated operating temperature range is -40C to 85C.
