Linear Tech Unveils 10A DC-DC Military Plastic "MicroModule" Regulator
Linear Technology Corp. introduced the LTM4600HVMPV, a complete and encapsulated 10A switching dc-dc regulator system, the first device in a new family of uModule™ (micromodule) dc-dc regulators designed for rugged military and avionics applications.
The LTM4600HVMPV is fully tested over the temperature range of -55 to 125°C. This device is offered in a 15mm x 15mm x 2.8mm Military Plastic LGA (Land Grid Array) package. The compact LGA package has been qualified by military system designers as the preferred package for high power dc-dc solutions because of its lower thermal impedance when compared to a similar size BGA (Ball Grid Array) package. Comprised entirely of Linear Technology silicon and supported by rigorous in-house testing, the LTM4600HVMPV is said to bring component-level reliability and industry-leading performance to demanding applications such as military and aerospace systems.
The LTM4600HVMPV is a synchronous switchmode dc-dc step-down regulator with built-in inductor, supporting power components and compensation circuitry. The device operates from an input supply range of 4.5 to 28V and regulates an output voltage from 0.6 to 5V. This dc-dc uModule regulator can deliver 10A continuous load current (14A peak) and achieve efficiencies as high as 92%. A dc-dc uModule regulator such as the LTM4600HVMPV simplifies power supply design and construction, requiring only input and output bulk capacitors and a resistor to set the output voltage.
The LTM4600HVMPV dc-dc uModule regulator weighs only 1.7g and is housed in a surface-mount package that can be handled and assembled like a standard integrated circuit. Moreover, its low profile design permits the device to be soldered onto the back side of a printed circuit board, freeing valuable board space for sophisticated digital ICs. The LTM4600HVMPV is self-protected against output overvoltage and short circuit conditions. 1,000-piece pricing starts at $36.95 each.
