The Analog Devices LTM46xx µ Module voltage regulator is a system in package (SiP) power management solution, available in a compact surface mount BGA or LGA package, featuring an integrated DC-DC controller, inductor, power transistor, compensation element, input and output capacitors. The LTM46xx µ Module regulator supports various functions such as step-down, step-up, and step-down step-up, and has multiple features. Some products are low EMI solutions that comply with EN55022 Class B standards, CISPR 22 (Class B), and CISPR 25 (Class 5). These µ Module power products adopt a compact and highly integrated design, which not only breaks through the limitations of time and space, but also provides highly reliable and efficient performance.
