Power density packs into compact 15mm x 15mm format

The new µModule from Linear Technology provides designers with a 10A switching power supply in a 15mm x 15mm footprint, 2.8mm land grid array (LGA) package. The LTM4600 is a synchronous switchmode DC/DC step-down regulator with built-in inductor, supporting power components and compensation circuitry.

The LTM4600 DC/DC µModule is a stand-alone, surface-mount power supply that can be handled and assembled like a standard integrated circuit. Its low profile design permits the LTM4600 to be soldered onto the back of a circuit board, freeing board space. The µModules are self-protected against over-voltage and short circuit conditions.

The devices' transient response (up to 10A continuous current, with14A peak, at up to 92% efficiency) minimises bulk output capacitance and two LTM4600s can be operated in parallel, increasing load current capability to 20A. The LTM4600 accommodates an input voltage range of 4.5V to 28V.

The LTM4600 is offered in two versions: standard and high input voltage. The LTM4600EV operates from 4.5V to 20V, whereas the LTM4600HVEV has an operating voltage range from 4.5V to 28V.
