General Description
The AAT2158 SwitchReg is a 1.5A step-down con-
verter with an input voltage range of 2.4V to 5.5V
and an adjustable output voltage from 0.6V to V
IN
.
The 1.4MHz switching frequency enables the use
of small external components. The small footprint
and high efficiency make the AAT2158 an ideal
choice for portable applications.
The AAT2158 delivers 1.5A maximum output current
while consuming only 42μA of no-load quiescent
current. Ultra-low R
DS(ON)
integrated MOSFETs and
100% duty cycle operation make the AAT2158 an
ideal choice for high output voltage, high current
applications which require a low dropout threshold.
The AAT2158 provides excellent transient
response and high output accuracy across the
operating range. No external compensation com-
ponents are required.
The AAT2158 maintains high efficiency throughout
the load range. The AAT2158’s unique architecture
produces reduced ripple and spectral noise. Over-
temperature and short-circuit protection safeguard
the AAT2158 and system components from damage.
The AAT2158 is available in a Pb-free, space-sav-
ing 16-pin 3x3mm QFN package. The product is
rated over an operating temperature range of -40°C
to +85°C.
