MAX17067

低噪声、升压型DC-DC转换器

紧凑的高效boost转换器

概述

说明

MAX17067 boost转换器集成了高性能(1.2MHz)、电流模式、固定频率、脉宽调制(PWM)电路和片内0.15Ω n沟道MOSFET，提供高效率、快速响应的稳压器。

高开关频率(可选择640kHz或1.2MHz)可简化滤波，并提供更快的环路性能。外部补偿引脚为用户提供灵活的环路动态调整，允许使用微小、低等效串联电阻(ESR)陶瓷输出电容。器件可提供高达18V输出电压。

通过外部电容调整软启动，设置输入电流斜率。MAX17067提供节省空间的8引脚µMAX®封装。超小封装和高开关频率可使整个方案的高度小于1.1mm。
