2mm-High 5A Power Module in Thermally-Enhanced Package

March 20, 2016 by Jeff Shepard

Microchip Technology Inc. now offers an integrated switching power module designed specifically for height-constrained telecom, industrial and solid-state drive (SSD) applications. The new MIC45404 comes in a thermally-enhanced package that incorporates inductors and passive components into a single, molded power converter. The slim 10 x 6 x 2 mm package saves space in customers' designs, simplifies board design, and eliminates concern over passive components that may introduce unexpected EMI.

“Eliminating the need to select key components and simplifying the board layout to meet EMI specifications are benefits that address requirements our customers have voiced,” said Keith Pazul, senior manager of Microchip’s Analog Power and Interface Division. “Microchip’s low-profile MIC45404 is the newest extension of our power module product family that offers our customers one of the highest input voltage ratings and power densities available in the market.”

The MIC45404 incorporates one of the thinnest integrated magnetic inductors available in a 19V, 5A point-of-load buck converter. Integrated components include the controller, metal-oxide semiconductor field-effect transistors (MOSFETs), feedback path, and pwm switching regulator. The low profile of the MIC45404 module allows it to be placed on the back of a PCB, on a daughter card, or other placement where vertical height may be constrained in point-of-load power conversion, telecom and industrial applications.

The MIC45404 is available today for sampling and volume production, starting at $4.22 each in 10,000-unit quantities. The MIC45404 is offered in a 10 x 2 x 6 mm QFN package and offers pin-selectable output voltages, switching frequencies, and current limits providing further design flexibility and space savings.

Microchip today also introduced the MIC45404 Evaluation Kit (part #MIC45404YMP-EV) which enables application development with the integrated switching power module. This kit is available now for $55.00 from microchipDIRECT and any of Microchip’s authorized worldwide distributors.
