Product Overview

The LTC3709EUH#PBF is a 2-phase single output synchronous step-down Switching Regulator Controller uses a constant on-time, valley current control architecture to deliver very low duty cycles without requiring a sense resistor. Operating frequency is selected by an external resistor and is compensated for variations in input supply voltage. An internal phase-locked loop allows the LTC3709 to be synchronized to an external clock. A TRACK pin is provided for tracking or sequencing the output voltage among several LTC3709 chips or an LTC3709 and other DC/DC regulators. Soft-start is accomplished using an external timing capacitor. Fault protection is provided by an output overvoltage comparator and an optional short-circuit shutdown timer. The current limit level is user programmable. A wide supply range allows voltages as high as 31V to step down to 0.6V.
  • PolyPhase® Valley current mode controller
  • Synchronizable to an external clock with PLL
  • Coincident or ratiometric tracking
  • True remote sensing differential amplifier
  • High efficiency at both light and heavy loads
  • Power good output voltage monitor
  • 0.6V ±1% Reference
  • Adjustable current limit
  • Programmable soft-start and operating frequency
