MILPITAS, CA ­ July 22, 2015 ­ Linear Technology Corporation introduces the LTM4622, a dual 2.5A or single 5A
step­down µModule® (micromodule) regulator in a small and ultrathin package. Only three capacitors and two
resistors are required, and the solution occupies less than 1cm² single­sided or 0.5cm² on a double­sided 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 height­restricted systems such as PCIe and advanced mezzanine cards (AMC) for AdvancedTCA carrier cards in embedded computing systems.
With two independent 2.5A (3A peak) outputs, the LTM4622 allows current sharing to provide up to 5A load current. Multiple devices can be current shared for higher output current. The device has an input supply voltage range of
3.6V to 20V and can also be configured to operate from a 3.3V input supply. The LTM4622's output voltage range is
0.6V and 5.5V. Output voltage total DC accuracy is guaranteed at ±1.5% including load and line regulation from
­40°C to 125°C. The LTM4622's 1K­piece price starts at $7.15 each. For more information, visit www.linear.com/product/LTM4622.
