-55°C to 125°C Buck-Boost DC/DC uModule Regulator, up to 36VIN, 34VOUT & 98% Efficiency
MILPITAS, CA - September 21, 2010 - Linear Technology
Corporation introduces the LTM4609MP, a
buck-boost DC/DC uModule® system-in-a-package that is guaranteed
and tested for the wide -55°C to 125°C temperature range. The
LTM4609MP is designed to deliver precision regulation in demanding
environments in applications such as military, avionics, heavy
industrial machinery, and harsh environment sensors. These uModule
devices are backed by Linear Technology's rigorous reliability and
quality test standards (reports are available online at www.linear.com/4609).
The LTM4609MP is a high voltage and high efficiency DC/DC system in
a surface mount 15mm x 15mm x 2.8mm LGA (land grid array) package.
The device regulates an output voltage from a variable input
voltage greater than, less than or equal to the output voltage. The
LTM4609MP operates from 4.5VIN to 36VIN, regulates an output
voltage from 0.8V to 34V and can deliver an output power up to
100W. Included in this uModule regulator is a synchronous
buck-boost DC/DC controller, four N-channel MOSFETs, input and
output bypass capacitors and compensation circuitry in a small
plastic molded package. Only an inductor, feedback and sense
resistors, and bulk capacitors are required to implement a very low
profile, compact and high efficiency design. Application examples
are point-of-load and intermediate-bus regulation in networking,
industrial and automotive systems and high-power battery-operated
devices.
With the LTM4609MP's onboard proprietary 4-switch synchronous
MOSFET design, the device achieves up to 98.3% efficiency in boost
mode and up to 97.3% efficiency in buck mode (condition: VIN: 6.5V
to 36V, VOUT: 30V, IOUT: 2A). Pricing for 1,000-piece quantities
starts at $37.20 each. For more information, visit www.linear.com/4609.
