概述

说明

MAX17515为固定频率、降压型电源模块，封装在散热良好的系统级封装(siP)内，采用2.4V至5.5V输入电源供电，支持高达5A输出电流。器件带有开关模式电源控制器、双路n沟道MOSFET功率开关、完全屏蔽电感以及补偿元件。器件支持0.75V至3.6V可编程输出电压。高度集成大大减小了设计的复杂性、生产风险，实现了真正的”即插即用”电源方案，减小产品上市时间。

器件采用1MHz固定频率工作，仅需要小尺寸输入输出电容。内部误差放大器的输出具有固定增益，使输出电压根据负载电流进行调整。内部固定的数字式软启动限制了启动时输入的浪涌电流，器件在轻载时采用跳脉冲模式工作可提高轻载时的效率。

MAX17515采用增强散热型、紧凑的28引脚、10mm × 6.5mm x 2.8mm SiP封装，工作在-40°C至+85°C工业级温度范围。
