Linear Technology Corporation (Linear Technology), a manufacturer of linear integrated circuits, has introduced a new complete and encapsulated 200mA, 1A and 2A, 36V input switching DC/DC regulator systems, LTM8020MPV, LTM8022MPV and LTM8023MPV. Belonging to a family of rugged DC/DC uModule are designed to deliver precision regulation in demanding environments found with applications such as military, avionics, heavy industrial machines, and harsh environment sensors.

The new regulator systems are tested for extreme temperatures ranging from -55ºC to 125ºC. In addition to wide-temperature performance guarantee, these uModule regulators are enclosed in a plastic mold surface mount package protecting the circuit components against moisture, chemicals, gas, and scratches.

The LTM8020MPV, LTM8022 MPV and LTM8023MPV are 200mA, 1A and 2A 36V input uModule regulators housed in very compact land grid array (LGA) packages. The package dimensions are 6.25mm x 6.25mm x 2.3mm for the LTM8020 and 9mmx 11.25mm x 2.8mm for the LTM8022 and LTM8023. To ease a designer’s layout task, the 1A output LTM8022 and its 2A output version, the LTM8023, are made with identical layout and pin assignment, LGA packages have been qualified by several military system designers as a preferred package for a high power DC/DC solution because of its lower thermal impedance when compared to a similar size Ball Grid Array (BGA) package.

Low profile package permits the device to be soldered onto the back side of a printed circuit board, freeing valuable board space for sophisticated digital ICs. 1,000-piece prices for the LTM8020MPV, LTM8022MPV and LTM8023MPV start at $10.14, $14.23, and $16.28 each, respectively.
