The LTM4608A is a complete 8A switch mode DC/DC power supply with ±1.75% total output voltage error. Included in the package are the switching controller, power FETs, inductor and all support components. Operating over an input voltage range of 2.7V to 5.5V, the LTM4608A supports an output voltage range of 0.6V to 5V, set by a single external resistor. This high efficiency design delivers up to 8A continuous current (10A peak). Only bulk input and output capacitors are needed to complete the design.

The low profile package (2.82mm) enables utilization of unused space on the back side of PC boards for high density point-of-load regulation. The 0.630mm LGA pads with 1.27mm pitch simplify PCB layout by providing standard trace routing and via placement. The high switching frequency and current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The device supports frequency synchronization, programmable multiphase and/or spread spectrum operation, output voltage tracking for supply rail sequencing and voltage margining.

Fault protection features include overvoltage protection, overcurrent protection and thermal shutdown. The LTM4608A is offered in 9mm × 15mm × 2.82mm LGA and 9mm × 15mm × 3.42mm BGA packages. The LTM4608A is available with SnPb (BGA) or RoHS compliant terminal finish.

Notes
LTM4608 -
LTM4608A Smaller pad sizes provide more distance between adjacent pads therefore there is less chance of solder paste or solder spreading outside the pad area
