LTM4607EV DC to DC Converter and Switching Regulator Chip 11.76VDC to 12.24VDC Output Demonstration Circuit

The demonstration board features LTM4607EV DC to DC µModule regulator. The LTM4607EV is a high efficiency switching mode buck boost power supply. Included in the IC package are the switching controller, power FETs and support components. The low profile package enables utilization of unused space on the bottom of PC boards for high density point of load regulation. The LTM4607EV can regulate its output voltage from input voltage both above and below the output. The board accepts an input voltage from 6V to 36V and is set for an output voltage of 12V. The rated load current is 5A in boost mode and 12A in step down operation. Derating is necessary for certain VIN, VOUT and thermal conditions. The switching frequency can be synchronized to external clock operating from 200KHz to 400KHz. This clock input can be used to reduce undesirable frequency harmonics and reduce input and output ripple when paralleling LTM4607EV for even higher output current.
