Product Overview

The LT3437IFE#PBF is a monolithic buck Switching Regulator accepts input voltage up to 80V. A high efficiency 500mA, 0.8R 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 along with 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. Burst Mode® operation can be defeated by a logic high signal on the SYNC pin which results in lower light load ripple at the expense of light load efficiency. Patented circuitry maintains peak switch current over the full duty cycle range. Shutdown reduces input supply current to less than 1µA.
  • Defeatable Burst Mode® operation

  • Easily synchronizable
  • Soft-start capability
  • Load dump (input transient) protection to 80V
  • 100µA Quiescent current
  • 0.8R On-resistance saturating switch design
  • 1.25V Feedback reference voltage
