ADP2503CPZ-REDYKIT: 3.3 and 5V @ 600mA, 2.3 ~ 5V in

Summary

The ADP2503/ADP2504 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 provides accurate (±2%) regulation for load currents of up to 1 A. The ADP2503/ ADP2504 evaluation boards are available for all output voltages. Additional voltage options are available upon request from Sales at Analog 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.
