The LTM®4655 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.
