Description

General part information

LTM4655 Series

The LTM4655 is an ultralow noise 40V, dual 4A or single 8A DC/DC μModule®regulator designed to meet the radiated emissions requirements of EN55022. Its channels are fully independent, parallelable and capable of delivering positive or negative output polarity. Conducted emission requirements can be met by adding standard filter components. Included in the package are the switching controllers, power MOSFETs, inductors, filters and support components. A 5V, 25mA LDO and clock generator enable phase interleaving of the power switching stages, for improved EMC performance.The LTM4655 can regulate positive VOUTn+voltages between 0.5V and 26.5V from a 3.1V to 40V input. The LTM4655 can regulate negative VOUTn–voltages between –0.5V and –26.5V from a maximum input range of 3.6V to 40V, with the span from VINnto VOUTn–not to exceed 40V. A switching frequency range of 250kHz to 3MHz is supported.The LTM4655 is offered in a 16mm × 16mm × 5.01mm BGA package with SnPb or RoHS compliant terminal finish.APPLICATIONSAutomated Test and MeasurementAvionics and Industrial Control SystemsVideo, Imaging and Instrumentation
