LTM8049 Typical Application


The LTM8049 is a Dual SEPIC/Inverting μModule® (power module) DC/DC Converter. Each of the two outputs can be easily configured as a SEPIC or Inverting converter by simply grounding the appropriate output rail. The LTM8049 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.

The LTM8049 is packaged in a thermally enhanced, compact (15mm × 9mm) over-molded Ball Grid Array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8049 is RoHS compliant.
