LTM8049

Dual SEPIC or Inverting

µModule DC/DC Converter

FEATURES

DESCRIPTION

TheLTM^®8049isaDualSEPIC/InvertingµModule^®(power

module) DC/DC Converter. Each of the two outputs can

be easily configured as a SEPIC or Inverting converter by

simplygroundingtheappropriateoutputrail.TheLTM8049

includes power devices, inductors, control circuitry and

passive components. All that is needed to complete the

design are input and output caps, and small resistors to

set the output voltages and switching frequency. Other

components may be used to control the soft-start and

undervoltage lockout.

Two Complete Switch Mode Power Supplies

SEPIC or Inverting Topology

Wide Input Voltage Range: 1.6V to 10V

1.5V to 14V or –1.5V to –14V Output Voltage

±A at 5V

from ±1V

OUT

Selectable Switching Frequency: 100kHz to 1.5MHz

Power Good Outputs for Event Based Sequencing

User Configurable Undervoltage Lockout

(e4) RoHS Compliant Package with Gold Pad Finish

Low Profile 15mm × 9mm × 2.42mm Surface Mount

BGA Package

The LTM8049 is packaged in a thermally enhanced, com-

pact (15mm × 9mm) over-molded Ball Grid Array (BGA)

packagesuitableforautomatedassemblybystandardsur-

face mount equipment. The LTM8049 is RoHS compliant.
