概述

说明

MAX15034是双相、可配置的单路或双路输出buck控制器，输入电压范围为4.75V至5.5V或5V至28V。模式选择输入可将器件设置为双路输出电源，或将两相连接在一起构成单路输出、大电流电源。MAX15034的每一路输出通道可驱动n沟道MOSFET，并能提供大于25A的负载电流。MAX15034采用平均电流模式控制，每相的开关频率高达1MHz，两相之间呈180°错相工作模式。错相工作模式大大降低了双相、单路输出电压应用中的输入电容纹波电流和输出电压纹波。每路控制器都具有高性能的电流和电压误差放大器，可为实现最优的输出滤波器L-C取值和瞬态响应提供补偿。

MAX15034提供两路使能输入，具有精确的导通门限，可实现两路输出电压的排序。该器件的开关频率可通过外部电阻编程设置，范围为100kHz至1MHz。MAX15034可同步至外部时钟。每路输出电压在0.61V至5.5V范围内可调。此外，该器件还包括热关断和打嗝模式短路保护功能。在要求快速瞬态响应或精确调节输出电压的应用中，可采用带自适应电压定位的MAX15034。

MAX15034采用增强散热型28引脚TSSOP封装，能够耗散2.1W功率。器件工作在-40°C至+125°C汽车级温度范围。
