LTM8058 3.1V to 31V Isolated IN IN Module DC/DC Converter with LDO Post Regulator FEATURES DESCRIPTION n 2kV AC Isolated Module Converter The LTM 8058 is a 2kV AC isolated flyback Module (Tested to 3kVDC) (micromodule) DC/DC converter with LDO post regulator. n UL60950 Recognized File E464570 Included in the package are the switching controller, power n Wide Input Voltage Range: 3.1V to 31V switches, transformer, LDO, and all support components. n V Output: Operating over an input voltage range of 3.1V to 31V, the OUT1 Up to 440mA (V = 24V V = 2.5V) LTM8058 supports an output voltage range of 2.5V to 13V, IN , OUT1 2.5V to 13V Output Range set by a single resistor. There is also a linear post regulator n V Low Noise Linear Post Regulator: whose output voltage is adjustable from 1.2V to 12V as OUT2 Up to 300mA set by a single resistor. Only output and input capacitors 1.2V to 12V Output Range are needed to finish the design. Other components may n Current Mode Control be used to control the soft-start control and biasing. n Programmable Soft-Start The LTM8058 is packaged in a thermally enhanced, com- n User Configurable Undervoltage Lockout pact (9mm 11.25mm 4.92mm) overmolded ball grid n Low Profile (9mm 11.25mm 4.92mm) array (BGA) package suitable for automated assembly BGA Package by standard surface mount equipment. The LTM8058 is available with SnPb or RoHS compliant terminal finish. L, LT, LTC, LTM, Linear Technology, the Linear logo and Module are registered trademarks of APPLICATIONS Analog Devices, Inc.
