DATA SHEET AAT2522 Dual High-Current, Low-Noise, Step-Down Regulator General Description The AAT2522 is a SwitchReg, dual, high-current, stepdown converter with an input voltage range of 2.7V to 5.5V and an adjustable output voltage from 0.6V to VIN. The 1.4MHz switching frequency enables the use of small external components. The compact footprint and high efficiency make the AAT2522 an ideal choice for portable applications. The AAT2522 delivers load currents up to 3.0A maximum output current per regulator. Ultra-low RDS(ON) integrated MOSFETs and 100% duty cycle operation make the AAT2522 an ideal choice for high output-voltage, high current applications which require a low dropout threshold.
