ADP2504-3.3-EVALZ，用于 ADP2504ACPZ-3.3-R7、1A、3.3V 降压升压转换器的评估板

使用 Analog Devices 的 ADP2504ACPZ-3.3-R7 的参考设计

设计简介

ADP2504-3.3-EVALZ，ADP2503 高效率、低静态电流升压、降压 DC-DC 转换器的评估板。这些转换器可为高达 1A 的负载电流提供精确 (±2%) 调节。 ADP2503 评估板适用于所有输出电压。在高负载电流下，ADP2503 采用电流模式、固定频率 PWM 控制方案，具有出色的稳定性和瞬态响应。为了确保便携式应用中的最长电池寿命，ADP2503具有可选的省电脉冲跳跃模式，可降低轻负载条件下的开关频率以节省功耗

说明

ADP2504-3.3-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
