Product Overview

The LT8580HMS8E#PBF is a PWM DC-to-DC Converter with 1A/65V switch, integrated soft-start function and synchronization. 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 synchronized to an external clock. The switching frequency 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 adjustable undervoltage lockout function. Additional features such as frequency foldback and soft-start are integrated.
  • Adjustable switching frequency
  • Single feedback resistor sets VOUT
  • High gain /SHDN pin accepts slowly varying input signals
  • User configurable undervoltage lockout (UVLO)
  • Pin compatible with LT3580
  • 400mV at 0.75A Typical low VCESAT switch
