Product Overview

The LT3580EMS8E#PBF is a Boost/Inverting DC/DC Converter with 2A switch, soft-start and synchronization. The LT3580 can be configured as either a boost, SEPIC or inverting converter. Capable of generating 12V at 550mA or -12V at 350mA from a 5V input, it is ideal for many local power supply designs. The LT3580 has an adjustable oscillator, set by a resistor from the RT pin to ground. Additionally, the LT3580 can be synchronized to an external clock. The free running or synchronized switching frequency range of the part can be set between 200kHz and 2.5MHz. The LT3580 also features innovative SHDN pin circuitry that allows for slowly varying input signals and an adjustable under-voltage lockout function. Additional features such as frequency fold back and soft-start are integrated.
  • 2A Internal power switch
  • Adjustable switching frequency
  • Single feedback resistor sets VOUT
  • Synchronizable to external clock
  • High gain SHDN pin accepts slowly varying input signals
  • Low VCESAT switch (300mV at 1.5A typical)
  • Integrated soft-start function
  • Easily configurable as a boost or inverting converter
  • User configurable under-voltage lockout (UVLO)
