说明

MAX15015A评估板(EV kit)是一块经过完全安装与测试的PCB,用于评估PWM/PFM降压转换器MAX15015A的性能,该转换器集成了一个高边开关和一个LDO稳压器。MAX15015A评估板可工作在较宽的4.5V至40V输入电压范围。在输出3.3V时可提供高达1A电流。在5V预设输出时,LDO稳压器可提供50mA电流。MAX15015A具有欠压锁定、过流和过热关断保护功能。

MAX15015A通常工作在PWM模式,在轻载时自动切换为PFM模式以提高效率。MAX15015A的开关频率预设为500kHz,并且具有SYNC输入,可在噪声敏感应用中同步至外部频率。评估板提供了PCB焊盘用于评估MAX15015A的SYNC和ENABLE特性。评估板还可用于评估MAX15015B。MAX15015A可工作于-40°C至+125°C汽车级温度范围。
