Linear Technology Corporationintroduces the LTM4622, a dual 2.5A or single 5A step-down µModule® (micromodule) regulator in a small and ultrathin package. Only three capacitors and two resistors are required, and the solution occupies less than one square centimeter single-sided or half a square centimeter on a double-sided PCB. Housed in a 6.25mm x 6.25mm x 1.82mm LGA package, the LTM4622 includes the switching dc-dc regulator, MOSFETs, inductors and supporting circuitry.

The ultrathin package allows the LTM4622 to be mounted on the backside of the PCB, freeing space on the topside for components such as memory and FPGAs. This makes the LTM4622 suitable for height-restricted systems such as PCIe and advanced mezzanine cards (AMC) for AdvancedTCA carrier cards in embedded computing systems.
