The LTM8047 has an isolation rating of 725VDC. For a similar product with LDO post regulator, see the LTM8048. Included in the package are the switching controller, power switches, transformer, and all support ponents. Operating over an input voltage range of 3.1V to 32V, the LTM8047 supports an output voltage range of 2.5V to 12V, set by a single resistor. Only output, input, and bypass capacitors are needed to finish the design. Other ponents may be used to control the soft-start control and biasing. The LTM8047 is packaged in a thermally enhanced, pact (11.25mm × 9mm × 4.92mm) over-molded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8047 is available with Sn Pb (BGA) or Ro HS pliant terminal finish. L, LT, LTC, LTM, Linear Technology, the Linear logo and µModule are registered trademarks of Linear Technology Corporation.
