DESCRIPTION

μModule is a trademark of Linear Technology Corporation. All other trademarks are the

property of their respective owners.

The LTM

supply. Included in the package are the switching control-

ler, power switches, inductor, and all support components.

Operating over an input voltage range of 3.6V to 36V, the

LTM8022 supports an output voltage range of 0.8V to 10V,

and a switching frequency range of 200kHz to 2.4MHz,

each set by a single resistor. Only the bulk input and output

ﬁ lter capacitors are needed to ﬁ nish the design.

The low proﬁ le package (2.82mm) enables utilization of

unused space on the bottom of PC boards for high density

point of load regulation.

The LTM8022 is packaged in a thermally enhanced, compact

(11.25mm × 9mm) and low proﬁ le (2.82mm) overmolded

Land Grid Array (LGA) package suitable for automated

assembly by standard surface mount equipment. The

LTM8022 is RoHS compliant.
