.. LTM4604A Low Voltage, 4A DC/DC µModule with Tracking DESCRIPTION The LTM®4604A is a plete 4A 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 ponents. Operating over an input voltage range of 2.375V to 5.5V, the LTM4604A supports an output voltage range of 0.8V to 5V, set by a single resistor. This high efficiency design delivers up to 4A continuous current (5A peak). Only bulk output capacitors are needed to plete the design. The 0.630mm LGA pads with 1.27mm pitch simplify PCB layout by providing standard trace routing and via placement. (The LTM4604A has smaller pads than the LTM4604.) The low profile package (2.3mm) enables utilization of unused space on the bottom of PC boards for high density point of load regulation. High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. Fault protection Features include foldback current protection, thermal shutdown and a programmable soft-start function. The LTM4604A is offered in a small thermally enhanced 15mm × 9mm × 2.3mm LGA package and is Pb free and Ro HS pliant.
