EN5322Q PowrSoC
DESCRIPTION
Thank you for choosing Altera Enpirion power
products!
The EN5322 evaluation board is configured to
provide a 1.2V output at up to 2A from a 2.4 V
to 5.5 V input. The output can be set to 7
different voltages through the three VID output
voltage select pins. It can also be adjusted
from 0.6V to (V
IN
–
0.2 x I
LOAD
) through the
external resistor divider option.
The 4 MHz operation allows for the use of tiny
MLCC capacitors. It also enables a very wide
control loop bandwidth providing excellent
transient performance and reduced output
impedance. The internal compensation is
designed for unconditional stability for all
operating conditions. The Power OK signal is
available.
