Product Overview

The LT3434EFE#PBF is a monolithic buck Switching Regulator accepts input voltage up to 60V. A high efficiency 3A, 0.1R switch is included on the die along with all the necessary oscillator, control and logic circuitry. Current-mode topology is used for fast transient response and good loop stability. Innovative design techniques integrated in a new high voltage process achieve high efficiency over a wide input range. Efficiency is maintained over a wide output current range by employing Burst Mode® operation at low currents, utilizing the output to bias the internal circuitry and by using a supply boost capacitor to fully saturate the power switch. Patented circuitry maintains peak switch current over the full duty cycle range. Shutdown reduces input supply current to less than 1µA. External synchronization can be implemented by driving the SYNC pin with logic-level inputs. A single capacitor from the CSS pin to the output provides a controlled output voltage ramp (soft-start).
  • Power good flag with programmable threshold
  • Peak switch current maintained over full duty cycle range
  • Easily synchronizable
  • Soft-start capability
  • 100µA Quiescent current
  • 60V Load dump protection
  • 0.1R Saturating switch design
  • 1.25V Feedback reference voltage
