LTM8057 3.1VIN to 31VIN Isolated µModule DC/DC Converter Features DESCRIPTION n 2k V AC Isolated µModule Converter (Tested at 3k VDC) n UL60950 Recognized File 464570 n Wide Input Voltage Range: 3.1V to 31V n Up to 440m A Output Current (VIN = 24V, VOUT1 = 2.5V) Output Adjustable from 2.5V to 12V n Current Mode Control n Programmable Soft-Start n User Configurable Undervoltage Lockout n Low Profile (9mm × 11.25mm × 4.92mm) BGA Package APPLICATIONS n Industrial Sensors n Industrial Switches n Test and Measurement Equipment The LTM®8057 is a 2k V AC isolated flyback µModule® (micromodule) DC/DC converter. 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 31V, the LTM8057 supports an output voltage range of 2.5V to 12V, set by a single resistor. Only output and input capacitors are needed to finish the design. Other ponents may be used to control the soft-start control and biasing. The LTM8057 is packaged in a thermally enhanced, pact (9mm × 11.25mm × 4.92mm) overmolded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8057 is available with Sn Pb or Ro HS pliant terminal finish. L, LT, LTC, LTM, Linear Technology, the Linear logo and µModule are registered trademarks of Analog Devices, Inc.
