GENERAL DESCRIPTION
The ADP2503/ADP2504 evaluation boards are complete buck
boost converter solutions that test the
boost converter solutions that test the
, high
efficiency, low quiescent current step-up/step-down, dc-to-dc
converters. These converters provides accurate (±2%) regulation
for load currents of up to 1 A. The ADP2503/ ADP2504 evalua-
tion boards are available for all output voltages. Additional
voltage options are available upon request from Sales at Analog
Devices, Inc.

Devices, Inc.
At high load currents, the ADP2503/ADP2504 use a current-
mode, fixed frequency PWM control scheme for excellent
stability and transient response. To ensure the longest battery
life in portable applications, the ADP2503/ADP2504 feature
an optional power-saving pulse skip mode that reduces the
switching frequency under light load conditions to save power.
