The LTM4605 is a high efficiency switching mode buckboost power supply. Included in the package are the switching controller, power FETs, and support components. Operating over an input voltage range of 4.5V to 20V, the LTM4605 supports an output voltage range of 0.8V to 16V, set by a resistor. This high efficiency design delivers up to 5A continuous current in boost mode (12A in buck mode). Only the inductor, sense resistor, bulk input and output capacitors are needed to finish the design.

The low profile package enables utilization of unused space on the bottom of PC boards for high density point of load regulation. The high switching frequency and current mode architecture enable a very fast transient response to line and load changes. The LTM4605 can be frequency synchronized with an external clock to reduce undesirable frequency harmonics.

Fault protection features include overvoltage and foldback current protection. The DC/DC μModule® regulator is offered in a small and thermally enhanced 15mm × 15mm × 2.8mm LGA package. The LTM4605 is Pb-free and RoHS compliant.

Product Detail

Demonstration circuit DC1198B-A features the LTM4605EV, the high efficiency, high density switch mode buck-boost μModule® regulator. The LTM4605EV can regulate its output voltage from an input voltage above, below, or equal to the output. The input voltage range of DC1198B-A is from 4.5V to 20V with a preset output voltage of 12V. The rated load current is 5A, although derating is necessary for certain VIN, VOUT, and thermal conditions. The switching frequency may be synchronized to an external clock from 200kHz to 400kHz. This PLL can be used not only to reduce undesirable frequency harmonics but also to parallel LTM4605 to provide high output current.
