SwitchReg
General Description
The AAT1106 SwitchReg is a 1.5MHz constant
frequency current mode PWM step-down convert-
er with a unique adaptive slope compensation
scheme allowing the device to operate with a lower
range of inductor values to optimize size and pro-
vide efficient operation. It is ideal for portable
equipment powered by single-cell Lithium-ion bat-
teries and is optimized for high efficiency, achiev-
ing levels up to 96%.
The AAT1106 can supply up to 600mA load current
from a 2.5V to 5.5V input voltage and the output
voltage can be regulated as low as 0.6V. The
device also can run at 100% duty cycle for low
dropout operation, extending battery life in portable
systems. In addition, light load operation provides
very low output ripple for noise sensitive applica-
tions and the 1.5MHz switching frequency mini-
mizes the size of external components while keep-
ing switching losses low.
The AAT1106 is available in adjustable and fixed
(1.5V, 1.8V) output voltage versions, comes in a
Pb-free, low-profile 5-pin TSOT23 package, and is
rated over the -40°C to +85°C temperature range.
