2A, 42V Boost Converter Now Offered in
High Temperature “H” & “MP” Grades
MILPITAS, CA – August 17, 2010 – Linear Technology announces the “H-grade” and
“MP-grade” versions of the LT3580, a current-mode, fixed frequency step-up DC/DC converter
with internal 2A, 42V switch. The device operates from an input voltage range of 2.5V to 32V,
making it suitable for applications with input sources ranging from a single-cell Li-Ion to
automotive inputs. The H-grade version operates with a junction temperature range of -40˚C to
150˚C, whereas the MP-grade operates with a junction temperature range of -55˚C to 125˚C.
This compares to the E- and I-grade versions’ 125˚C maximum junction temperature. All
electrical specifications are identical for the E, I, H and MP. The H-grade parts are both tested
and guaranteed to the junction temperature range of -40˚C to 150˚C and are ideal for automotive
and industrial applications, which are subject to high ambient temperatures. Similarly, the
MP-grade parts are tested and guaranteed to the junction temperature range of -55˚C to 125˚C
and are well suited for military and avionics applications, which are subject to both low and high
ambient temperatures.
The LT3580 can be configured as either a boost, SEPIC or an inverting converter. Its
switching frequency can be programmed, via a single resistor or synchronized to an external
clock, between 200kHz and 2.5MHz, enabling designers to minimize external component sizes
and to avoid “noise critical” frequency bands. The combination of a 3mm x 3mm DFN package
(or MSOP-8E) and tiny externals ensures a highly compact footprint while minimizing solution
cost.
The LT3580HMSE and the LT3580MPMSE are available from stock in thermally
enhanced MSOP-8E packages. Pricing starts at $2.77 and $8.31 each, respectively, for
1,000-piece quantities. For more information, visit www.linear.com/3580.
