ADP2504-EVALZ: 3V @ 1A, 2.3 ~ 5.5V in, Buck-Boost

Summary

The ADP2503/ADP2504 adjustable output voltage evaluation boards are complete buck-boost converter solutions that test the ADP2503/ADP2504, high efficiency, low quiescent current, step-up/step-down, dc-to-dc converters. These converters provide accurate (±2%) regulation for load currents up to 1 A.

The ADP2503/ADP2504 evaluation boards are available for all output voltages. Additional voltage options are available upon request from your local Analog Devices, Inc., sales office.

At high load currents, the ADP2503/ADP2504 uses 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.
