Overview
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.
The AAT2522 provides excellent transient response and high output accuracy across the operating range.
The AAT2522’s unique architecture requires no external compensation components, and produces reduced ripple and spectral noise.
Over-temperature and short-circuit protection safeguard the AAT2522 and system components from damage.
The AAT2522 is available in a Pb-free, space-saving 16-pin 3mm x 4mm TDFN package.
The product is rated over an operating temperature range of -40°C to +85°C.
