FEATURES

DC-to-DC Converters
ADP2503/ADP2504
GENERAL DESCRIPTION
The
ADP2503/ADP2504
are high efficiency, low quiescent current
step-up/step-down dc-to-dc converters that can operate at input
voltages greater than, less than, or equal to the regulated output
voltage. The power switches and synchronous rectifiers are
internal to minimize external device count. At high load currents,
the
ADP2503/ADP2504
use a current-mode, fixed frequency
pulse-width modulation (PWM) control scheme for optimal
stability and transient response. To ensure the longest battery life
in portable applications, the
ADP2503/ADP2504
have an optional
power save mode that reduces the switching frequency under
light load conditions. For wireless and other low noise applica-
tions where variable frequency power save mode may cause
interference, the logic control input sync forces fixed frequency
PWM operation under all load conditions.
The
ADP2503/ADP2504
can run from input voltages between
2.3 V and 5.5 V, allowing single lithium or lithium polymer cell,
multiple alkaline or NiMH cells, PCMCIA, USB, and other stan-
dard power sources. The
ADP2503/ADP2504
have fixed output
options, or using the adjustable model, the output voltage can
be programmed through an external resistor divider. Compensa-
tion is internal to minimize the number of external components.
During logic-controlled shutdown, the input is disconnected
from the output and draws less than 1 μA from the input source.
Operating as boost converters, the
ADP2503/ADP2504
feature a
true load disconnect function that isolates the load from the
power source. Other key features include undervoltage lockout
to prevent deep battery discharge, and soft start to prevent input
current overshoot at startup.
