Press Release

Linear Technology Corporation introduces the LTM4600HVMPV, a complete and encapsulated 10A switching DC/DC regulator system, the first device in a new family of µModule^™ (micromodule) DC/DC regulators designed for rugged military and avionics applications. The LTM4600HVMPV is fully tested over the temperature range of –55°C to 125°C. This device is offered in a 15mm × 15mm × 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 our rigorous in-house testing, the LTM4600HVMPV brings 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 4.5V to 28V and regulates an output voltage from 0.6V to 5V. This DC/DC µModule regulator can deliver 10A continuous load current (14A peak) and achieve efficiencies as high as 92%. A DC/DC µModule 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 µModule 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.
