LTM8033 DC to DC Converter and Switching Regulator Chip 3.201VDC to 3.399VDC Output Demonstration Circuit Automotive

The demonstration circuit features LTM8033EV DC to DC µModule Regulator. The LTM8033EV is an electromagnetic compatible EMC 36V, 3A DC to DC µModule buck converter designed to meet the radiated emissions requirements of EN55022. Conducted emission requirements can be met by adding standard filter components. Included in the IC package are the switching controller, power switches, inductor, filters and all support components. The circuit supports other features of the LTM8033EV including synchronization to an external clock, current sharing with another LTM8033EV µModule regulator and burst mode operation for improved efficiency at light loads.
