LTM8048EY#PBF

An isolated flyback µModule DC/DC converter with LDO post regulator. It has an isolation rating of 725VDC. Included in the package are the switching controller, power switches, transformer, and all support components. Operating over an input voltage range of 3.1V to 32V, it supports an output voltage range of 2.5V to 13V, set by a single resistor. There is also a linear post regulator whose output voltage is adjustable from 1.2V to 12V as set by a single resistor. Only output, input, and bypass capacitors are needed to finish the design. Other components may be used to control the soft-start control and biasing. It is packaged in a thermally enhanced, compact (11.25mm×9mm×4.92mm) over-molded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. It is available with SnPb (BGA) or RoHS compliant terminal finish.
