GENERAL DESCRIPTION
The ADP2325 is a full featured, dual output, step-down dc-to-dc
regulator based on a current mode architecture. The ADP2325
integrates two high-side power MOSFETs and two low-side drivers
for the external N-channel MOSFETs. The two pulse-width mod-
ulation (PWM) channels can be configured to deliver dual 5 A
outputs or a parallel-to-single 10 A output. The regulator operates
from input voltages of 4.5 V to 20 V, and the output voltage can
be as low as 0.6 V.
The switching frequency can be programmed from 250 kHz to
1.2 MHz, or it can be synchronized to an external clock to
minimize interference in multirail applications. The dual PWM
channels run 180° out of phase, thereby reducing input current
ripple as well as reducing the size of the input capacitor.
The bidirectional synchronization pin can be programmed at
a 60°, 90°, or 120° phase shift to provide for a stackable, multi-
phase power solution.
The ADP2325 can be configured to operate in pulse frequency
modulation (PFM) mode at a light load for higher efficiency or
in forced PWM mode for noise sensitive applications. External
compensation and soft start provide design flexibility.
Independent enable inputs and power-good outputs provide
reliable power sequencing. To enhance system reliability, the device
includes undervoltage lockout (UVLO), overvoltage protection
(OVP), overcurrent protection, and thermal shutdown.
The ADP2325 operates over the −40°C to +125°C junction
temperature range and is available in a 32-lead LFCSP_WQ
package.
