Analog Devices Inc. LTM4622/LTM4623降压型直流/直流μModule稳压器
Linear Technology/Analog Devices LTM4622/LTM4623超薄降压型直流/直流μModule稳压器可在高达20V的输入电压范围内工作，带外部偏置电源。LTM4622/LTM4623支持高达5.5V的输出电压范围（由单个外部电阻器设置）。得益于高效率设计，该器件能够提供2.5A/3A连续输出电流，仅需少量的陶瓷输入和输出电容器。可选的Burst Mode®操作或断续模式以及输出电压跟踪功能支持电源轨排序。对线路和负载变化的极快速瞬态响应实现了高开关频率和电流模式控制，而且未牺牲稳定性。LTM4622/LTM4623具有故障保护功能，如输入过压、输出过流和过温保护。μModule稳压器具有SnPb (BGA)或符合RoHS标准的端子涂层。
Supply rail sequencing is supported by selectable Burst Mode® operation or discontinuous mode and output voltage tracking. A very fast transient response to line and load changes enable the high switching frequency and current mode control to operate without sacrificing stability. The LTM4622/LTM4623 from Analog Devices Inc. includes fault protection features like input overvoltage, output overcurrent, and overtemperature protection. The μModule regulators are available with SnPb (BGA) or RoHS compliant terminal finish.
