36-V, 8-A step-down µModule regulator is certified to EN55022 Class B
Designed to accept an input voltage from 5 V to 36 V, the LTM4613 delivers a regulated output voltage from 3.3 V to 15 V with 2.0% maximum DC error over line, load and temperature. The converter achieves peak operating efficiencies above 95% in a 24 V to 12 V 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.
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 15 mm x 15 mm x 4.3 mm LGA package. Three temperature grades are available: E and I grades for the -40 to +125°C temperature range as well as the MP grade for operation over the -55 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.
