DESCRIPTION

1A, 36V DC/DC µModule

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

filter capacitors are needed to finish the design.

The low profile 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 profile (2.82mm) overmolded

Land Grid Array (LGA) package suitable for automated

assembly by standard surface mount equipment. The

LTM8022 is RoHS compliant.
