ADP2504-5.0-EVALZ, Evaluation Board for the ADP2503 high efficiency, low quiescent current step-up, step-down dc-to-dc converter. These converters provides accurate (±2%) regulation for load currents of up to 1A. The ADP2503 evaluation board is available for all output voltages. At high load currents, the ADP2503 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 feature an optional power-saving pulse skip mode that reduces the switching frequency under light load conditions to save power
