n Overcurrent/Overvoltage/Overtemperature Protectio 15mm × 9mm × 5.01mm BGA Package The LTM®4653 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. n APPLICATIONS Operating over an input voltage range of 3.1V to 58V, the
LTM4653 supports an output voltage range of 0.5V to
94% of VIN, and a switching frequency range of 250kHz
to 3MHz (400kHz default), each set by a single resistor. …
