www.DataSheet4U.com LTM4604A Low Voltage, 4A DC/DC µModule with Tracking DESCRIPTION The LTM®4604A is a complete 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 components. 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 complete 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.
