description

LTM^®The 4607 is a high efficiency switch-mode buck-boost power supply. The package includes the switching controller, power FETs, and supporting components. The LTM4607 operates from an input voltage range of 4.5V to 36V and supports an output voltage range of 0.8V to 24V, set by a single resistor. This high efficiency design provides up to 5A of continuous current in boost mode (10A in buck mode). Only an inductor, sense resistor, and bulk input and output capacitors are required to complete the design.

The low profile allows unused space on the bottom of the pc board to be utilized for high-density point-of-load regulation. The use of high switching frequency and current mode architectures enables fast transient response to voltage and load changes without sacrificing stability. The frequency of the LTM4607 can be synchronized with an external clock to reduce unwanted frequency harmonics.

Fault protection features include overvoltage and foldback current protection. The DC/DC μModule^®Available in a thermally enhanced 15mm x 15mm x 2.8mm LGA package in a small form factor. The LTM4607 is Pb-free and RoHS compliant.
