AAT2158

1. Stresses above those listed in Absolute Maximum Ratings may cause damage to the device. Functional operation at conditions other han the operating conditions specified is not implied. Only one Absolute Maximum Rating should be applied at any one time.

The AAT2158 SwitchReg is a 1.5A step-down converter ith an input voltage range of 2.4V to 5.5V

and an adjustable output voltage from 0.6V to V_IN. he 1.4MHz switching frequency enables the use f small external components. The small footprint nd high efficiency make the AAT2158 an ideal hoice for portable applications.

The AAT2158 delivers 1.5A maximum output current hile consuming only 42A of no-load quiescent urrent. Ultra-low RDS(ON) integrated MOSFETs and 00% duty cycle operation make the AAT2158 an deal choice for high output voltage, high current pplications which require a low dropout threshold.

The AAT2158 provides excellent transient esponse and high output accuracy across the perating range. No external compensation components re required.

The AAT2158 maintains high efficiency throughout he load range. The AAT2158's unique architecture roduces reduced ripple and spectral noise. Overtemperature nd short-circuit protection safeguard

the AAT2158 and system components from damage. he AAT2158 is available in a Pb-free, space-saving 6-pin 3x3mm QFN package. The product is ated over an operating temperature range of -40°C o +85°C.
