Additional Details

The LTM4653 is an ultralow noise 58V, 4A DC/DC stepdown μModule^® regulator designed to meet the radiated emissions requirements of EN55022. Conducted emission requirements can be met by adding standard filter components. Included in the package are the switching controller, power MOSFETs, inductor, filters and support components.

Operating over an input voltage range of 3.1V to 58V, the LTM4653 supports an output voltage range of 0.5V to 94% of V_IN, and a switching frequency range of 250kHz to 3MHz (400kHz default), each set by a single resistor. For high load currents, the LTM4653 can be paralleled in PolyPhase^® operation and synchronized to an external clock. Only the bulk input and output filter capacitors are needed to finish the design.

The LTM4653 is offered in a 15mm × 9mm × 5.01mm BGA package with SnPb or RoHS compliant terminal finish.
