Device Summary
The AAT2511 is a constant frequency peak current
mode PWM converter with internal compensation.
Each channel has independent input, enable, feed-
back, and ground pins with non-synchronized
1MHz clocks.
Both converters are designed to operate with an
input voltage range of 2.7V to 5.5V. The output
voltage ranges from 0.6V to the input voltage. The
0.6V fixed model shown in Figure 1 is also the
adjustable version and is externally programmable
with a resistive divider as shown in Figure 2. The
converter MOSFET power stage is sized for
600mA load capability with up to 97% efficiency.
Light load efficiency exceeds 80% at a 500μA load.
