DC1198A-B: 12V @ 5A, 6 ~ 36 Vin, Step Up/Down

Demonstration circuit DC1198A-B features the LTM®4607EV, a high efficiency, high density switch mode buck-boost power module. 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 LTM4607 modules for even higher output current. The LTM4607 data sheet must be read in conjunction with this demo manual for working on or modifying the demo circuit DC1198A-B.
