1 / 32 page  LT8580 1 8580fa For more information www.linear.com/LT8580 Typical applicaTion FeaTures applicaTions DescripTion Boost/SEPIC/Inverting DC/DC Converter with 1A, 65V Switch, Soft-Start and Synchronization The LT®8580 is a PWM DC/DC converter containing an internal 1A, 65V switch. The LT8580 can be configured as either a boost, SEPIC or inverting converter. The LT8580 has an adjustable oscillator, set by a resistor from the RT pin to ground. Additionally, the LT8580 can be synchronizedtoanexternalclock.Theswitchingfrequency of the part may be free running or synchronized, and can be set between 200kHz and 1.5MHz. The LT8580 also features innovative SHDN pin circuitry that allows for slowly varying input signals and an adjust- able undervoltage lockout function. Additional features such as frequency foldback and soft-start are integrated. The LT8580 is available in tiny thermally enhanced 3mm × 3mm 8-lead DFN and 8-lead MSOP packages. 1.5MHz, 5V to 12V Boost Converter n 1A, 65V Power Switch n Adjustable Switching Frequency n Single Feedback Resistor Sets VOUT n Synchronizable to External Clock n High Gain SHDN Pin Accepts Slowly Varying Input Signals n Wide Input Voltage Range: 2.55V to 40V n Low VCESAT Switch: 400mV at 0.75A (Typical) n Integrated Soft-Start Function n Easily Configurable as a Boost, SEPIC, or Inverting Converter n User Configurable Undervoltage Lockout (UVLO) n Pin Compatible with LT3580 n Tiny Thermally Enhanced 8-Lead 3mm × 3mm DFN and 8-Lead MSOP Packages n VFD Bias Supplies n TFT-LCD Bias Supplies n GPS Receivers n DSL Modems n Local Power Supply Efficiency and Power Loss L , LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and ThinSOT is a trademark of Linear Technology Corporation.
