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.
