FEATURES

DESCRIPTION

The LTM^®8023 is a complete 2A, DC/DC step-down power

supply. Included in the package are the switching control-

ler, powerswitches, inductor, andallsupportcomponents.

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

LTM8023 supports an output voltage range of 0.8V to 10V,

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

eachsetbyasingleresistor. Onlythebulkinputandoutput

ﬁlter capacitors are needed to ﬁnish the design.

Complete Step-Down Switch Mode Power Supply

Wide Input Voltage Range: 3.6V to 36V

2A Output Current

0.8V to 10V Output Voltage

Selectable Switching Frequency: 200kHz to 2.4MHz

Current Mode Control

(e4) RoHS Compliant Package with Gold

Programmable Soft-Start

Tiny, Low Proﬁle (11.25mm × 9mm × 2.82mm)

The low proﬁle package (2.82mm) enables utilization of

unused space on the bottom of PC boards for high density

point of load regulation.

Surface Mount LGA Package

TheLTM8023ispackagedinathermallyenhanced,compact

(11.25mm×9mm)andlowproﬁle(2.82mm)over-molded

Land Grid Array (LGA) package suitable for automated

assembly by standard surface mount equipment. The

LTM8023 is RoHS compliant.
