EN55022 Class B Certified 36V, 8A Step-Down uModule Regulator
MILPITAS, CA – May 16, 2011 – Linear Technology introduces the LTM4613, an 8A step-down µModule® regulator certified by TUV Rheinland an accredited laboratory, to meet EN55022 Class B EMI (electromagnetic interference) emissions limits at up to 96W of output power. Designed to accept an input voltage from 5V to 36V, the LTM4613 delivers a regulated output voltage from 3.3V to 15V with 2.0% maximum DC error over line, load and temperature. The converter achieves peak operating efficiencies above 95% in a 24V to 12V output application.
The LTM4613 delivers the highest output power in the EN55022
Class B certified family of µModule regulators. This performance is
made possible by an integrated pi-filter, meticulous layout,
shielded inductor and carefully controlled power transistor drive.
With the formal certificate and associated PCB layout files
available at
www.linear.com/product/LTM4613, the LTM4613 eliminates
the need for external filters, magnetic shields and ferrite beads
for a trouble-free design process. Also encapsulated within the
surfacemount plastic package are the step-down controller, power
transistors, inductor, compensation, input filter and a modest
amount of input and output capacitance. A clock input pin is
available to synchronize one or more LTM4613 regulators, which is
particularly useful when the highly accurate current sharing
feature is implemented. Additional features include externally
adjustable soft-start, output voltage margining and switching
frequency.
The LTM4613 is housed in a thermally efficient 15mm x 15mm x
4.3mm LGA package. Three temperature grades are available: E and I
grades for the -40°C to +125°C temperature range as well as the MP
grade for operation over
the -55°C to +125°C temperature range. Pricing starts at $24.40
each for 1,000-piece quantities and all temperature grades are
available for immediate delivery from stock. For more information
