PMIC - 4-Channel 5A Output Integrated Inductor DC-DC

4-channel output, and integrated inductor DC-DC, the most famous model should be the former Linear Technology’s LTM4644. The LTM4644 not only supports 4-channel 4A output but also has excellent current sharing, allowing for arbitrary combinations of parallel outputs among the four channels. It has been widely used in applications with size constraints and high reliability, … Read more
