µModule Regulators
Analog Devices’ dc-to-dc power products are complete system-in-package (SiP) power management solutions with integrated dc-to-dc controllers, power transistors, input and output capacitors, compensation components, and inductors within a compact, surface-mount BGA or LGA package. µModule power products support functions such as step-down (buck), step-down and step-up (buck-boost), battery charger, isolated converter, and LED driver. As a highly integrated solution with PCB Gerber files available for every device, µModule power products address time and space constraints while delivering a high efficiency, reliable, and, with select products, a low EMI solution compliant with EN 55022 Class B standards.
