说明

MAX17112是高性能、升压DC-DC转换器,为有源矩阵薄膜晶体管(TFT)液晶显示器(LCD)提供稳压电源。MAX17112采用电流模式、固定频率(1MHz)、脉宽调制(PWM)电路和内置n沟道功率MOSFET,具有高效率和快速瞬态响应。输入过压保护(OVP)功能可保护MAX17112在输入浪涌电压(高达24V)下不被损坏。

高开关频率(1MHz)允许使用超小型电感和低ESR陶瓷电容。电流模式架构可为脉冲负载提供快速瞬态响应。补偿引脚(COMP)为用户提供灵活的动态环路调整。内部MOSFET能够从2.6V至5.5V输入电压产生最大20V输出电压。

软启动功能缓慢提升输入电流,可由外部电容进行设置。MAX17112采用10引脚TDFN封装。
