Analog Devices Inc. LTM4624 4A降压型直流/直流μModule稳压器

Linear Technology/Analog Devices LTM4624 14VIN、4A降压型直流/直流μModule稳压器具有高效设计，能够提供4A（连续）、5A（峰值）输出电流。LTM4624支持0.6V至5.5V的输出电压范围（单个外部电阻器设置）。μModule稳压器可在4V至14V或2.375V至14V的输入电压范围内工作，带外部偏置电源。可选的断续模式操作和输出电压跟踪功能支持电源轨排序。LTM4624对线路和负载变化有着极快的速瞬态响应，采用高开关频率和电流模式控制，而且未牺牲稳定性。这款直流/直流μModule稳压器的故障保护功能包括过压、过流和过热保护。LTM4624具有SnPb (BGA)或符合RoHS标准的端子涂层。

Supply rail sequencing is supported through selectable discontinuous mode operation and output voltage tracking. Enabling a very fast transient response to line and load changes the LTM4624, uses high switching frequency and current mode control without sacrificing stability.

Overvoltage, overcurrent, and overtemperature protection are fault protection features for the DC/DC μModule regulators. SnPb (BGA) or RoHS compliant terminal finish are available for the LTM4624.
