LTM8046 3.1V to 31V , 2kVAC IN IN Isolated DC/DC Module Converter Fea T Descrip T n 2kVAC Isolated Module Converter (Tested to 3kVDC) The LTM 8046 is an isolated flyback DC/DC Module n UL 60950 Recognized , File E464570 (micromodule) converter. The LTM8046 has an isolation n Wide Input Voltage Range: 3.1V to 31V rating of 2kVAC. Included in the package are the switching n 5V at 550mA from 24V controller, power switches, transformer, and all support IN n 1.8V to 12V Output Voltage components. Operating over an input voltage range of 3.1V n Current Mode Control to 31V, the LTM8046 supports an output voltage range n Programmable Soft-Start of 1.8V to 12V, set by one resistor. Only output, input, n User Configurable Undervoltage Lockout and bias capacitors are needed to finish the design. An n SnPb or RoHS Compliant Finish optional capacitor can be used to set the soft-start period. n 9mm 15mm 4.92mm BGA Package The LTM8046 is packaged in a 9mm 15mm 4.92mm over-molded ball grid array (BGA) package suitable for a T automated assembly by standard surface mount equip- ment. The LTM8046 is available with SnPb (BGA) or RoHS n Industrial Sensors compliant terminal finish. n Industrial Switches L, LT, LTC, LTM, Linear Technology, the Linear logo and Module are registered trademarks of n Ground Loop Mitigation Linear Technology Corporation.
